There is no such thing as a 'highest common multiple', but the least common multiple or LCM can be found using prime numbers. The LCM of the given numbers is the product of all different prime factors to their greatest power. If there are no exponents, the greatest power of the prime factors is 1 and each different prime factor is used in the multiplication:
prime factors of 210 are 2 x 3 x 5 x 7;
prime factors of 147 are 3 x 72;
the LCM of 210 and 147 is 2 x 3 x 5 x 72 = 1470

What is the least common multiple of two different prime numbers?
The least common multiple of two different prime numbers is the product of those two prime numbers.
What least common multiple equals the product of the two numbers?
If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.
What is the least common multiple of 2149?
There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
What is the least common multiple of 14 and 26?
LCM is 182, which is the multiple of the highest power of prime factors in the given numbers (2 x 7 x 13).
What is the least common multiple of 3033?
There is no LCM of a single number. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
