Given numbers are 639, 185, 451, 292
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 185) = 118215
GCD(639, 185) = ( 639 x 185 ) / 118215
= 639 / 185
= 639
Step2:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
Step3:
LCM(1, 292) = 292
GCD(1, 292) = ( 1 x 292 ) / 292
= 1 / 292
= 1
So, Greatest Common Divisor of 639, 185, 451, 292 is 1
