Least Common Multiple of 62 and 47

Least common multiple or lowest common denominator (LCD) can be calculated in three ways;

• Least Common Multiple of 62 and 47 by Prime method
• Least Common Multiple of 62 and 47 with GCF Formula

Least common multiple can be found by multiplying the highest exponent prime factors of 62 and 47. First we will calculate the prime factors of 62 and 47.

Prime Factorization of 62

Prime factors of 62 are 2,31. Prime factorization of 62 in exponential form is:

62 = 2¹×31¹

Prime Factorization of 47

Prime factors of 47 are 47. Prime factorization of 47 in exponential form is:

47 = 47¹

Now multiplying the highest exponent prime factors to calculate the LCM of 62 and 47.

LCM(62,47) = 2¹×31¹×47¹
LCM(62,47) = 2914

Factors of 62

List of positive integer factors of 62 that divides 62 without a remainder.

1, 2, 31, 62

Factors of 47

List of positive integer factors of 47 that divides 47 without a remainder.

1, 47

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 62 and 47, than apply into the LCM equation.

GCF(62,47) = 1
LCM(62,47) = ( 62 × 47) / 1
LCM(62,47) = 2914 / 1
LCM(62,47) = 2914

(i) The LCM of 47 and 62 is associative
