Steps to Calculate GCD of 715, 947, 180, 815 using LCM Formula

Given numbers are 715, 947, 180, 815

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(715, 947) = 677105

GCD(715, 947) = ( 715 x 947 ) / 677105

= 715 / 947

= 715


Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1


Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1


So, Greatest Common Divisor of 715, 947, 180, 815 is 1
