Given numbers are 640, 139, 125, 591
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 139) = 88960
GCD(640, 139) = ( 640 x 139 ) / 88960
= 640 / 139
= 640
Step2:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
Step3:
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
= 1 / 591
= 1
So, Greatest Common Divisor of 640, 139, 125, 591 is 1
