Steps to Calculate GCD of 263, 242, 157, 561 using LCM Formula
Given numbers are 263, 242, 157, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(263, 242) = 63646
GCD(263, 242) = ( 263 x 242 ) / 63646
= 263 / 242
= 263
Step2:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 263, 242, 157, 561 is 1
