Given numbers are 647, 556, 689, 540
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 556) = 359732
GCD(647, 556) = ( 647 x 556 ) / 359732
= 647 / 556
= 647
Step2:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
Step3:
LCM(1, 540) = 540
GCD(1, 540) = ( 1 x 540 ) / 540
= 1 / 540
= 1
So, Greatest Common Divisor of 647, 556, 689, 540 is 1
