Given numbers are 639, 652, 311, 151
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 652) = 416628
GCD(639, 652) = ( 639 x 652 ) / 416628
= 639 / 652
= 639
Step2:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
Step3:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
So, Greatest Common Divisor of 639, 652, 311, 151 is 1
