Steps to Calculate GCD of 253, 429, 815, 157 using LCM Formula
Given numbers are 253, 429, 815, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(253, 429) = 9867
GCD(253, 429) = ( 253 x 429 ) / 9867
= 253 / 429
= 253
Step2:
LCM(11, 815) = 8965
GCD(11, 815) = ( 11 x 815 ) / 8965
= 11 / 815
= 11
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 253, 429, 815, 157 is 1
