Given numbers are 928, 711, 647, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(928, 711) = 659808
GCD(928, 711) = ( 928 x 711 ) / 659808
= 928 / 711
= 928
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 928, 711, 647, 556 is 1
