Given numbers are 561, 658, 271, 679
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 658) = 369138
GCD(561, 658) = ( 561 x 658 ) / 369138
= 561 / 658
= 561
Step2:
LCM(1, 271) = 271
GCD(1, 271) = ( 1 x 271 ) / 271
= 1 / 271
= 1
Step3:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
So, Greatest Common Divisor of 561, 658, 271, 679 is 1
