Given numbers are 558, 663, 977, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 663) = 123318
GCD(558, 663) = ( 558 x 663 ) / 123318
= 558 / 663
= 558
Step2:
LCM(3, 977) = 2931
GCD(3, 977) = ( 3 x 977 ) / 2931
= 3 / 977
= 3
Step3:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
So, Greatest Common Divisor of 558, 663, 977, 422 is 1
