The common multiples of 3 and 7 up to 70 are 21, 42, and 63. A a couple of of a host a is a number that’s the product of a and some other quantity.
Factors of 12 = 1, 2, 3, 4, 6 and 12. Factors of 18 = 1, 2, 3, 6, 9 and 18. Therefore, common issue of 12 and 18 = 1, 2, 3 and 6. Highest common issue (H.C.F) of 12 and 18 = 6 [since 6 is the best common factor].

What is the HCF of 15?
Factors of 15 (Fifteen) = 1, 3, 5 and 15. Factors of 35 (Thirty five) = 1, 5, 7 and 35. Therefore, common factor of 15 (Fifteen) and 35 (Thirty five) = 1 and 5. Highest common factor (H.C.F) of 15 (Fifteen) and 35 (Thirty 5) = 5.
What is the LCM of 15 and 20 and 30?
The least common more than one 60 is a product of common & abnormal prime components between the integers which is divisible by way of each one an integer of this similar staff. The step by step paintings for LCM of 15, 20 and 30 might useful to understand how to seek out LCM for 2 or three numbers.
A host will have so much of components. 20 additionally has 1, 2 and 10 as elements because 1 x 20 and 2 x 10 also equivalent 20. The highest common issue of two numbers is the biggest whole quantity which is an element of both. This can every so often also be referred to as the Greatest Common Factor (GCF).
Final Step: Biggest Common Factor Number We discovered the factors and prime factorization of 10 and 20. The greatest common issue number is the GCF number. So the greatest common factor 10 and 20 is 10.
