Steps to Calculate GCD of 557, 290, 157, 763 using LCM Formula
Given numbers are 557, 290, 157, 763
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 290) = 161530
GCD(557, 290) = ( 557 x 290 ) / 161530
= 557 / 290
= 557
Step2:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
Step3:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
So, Greatest Common Divisor of 557, 290, 157, 763 is 1
