Given numbers are 640, 556, 269, 662
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 556) = 88960
GCD(640, 556) = ( 640 x 556 ) / 88960
= 640 / 556
= 640
Step2:
LCM(4, 269) = 1076
GCD(4, 269) = ( 4 x 269 ) / 1076
= 4 / 269
= 4
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 640, 556, 269, 662 is 1
