Given numbers are 497, 355, 812, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(497, 355) = 2485
GCD(497, 355) = ( 497 x 355 ) / 2485
= 497 / 355
= 497
Step2:
LCM(71, 812) = 57652
GCD(71, 812) = ( 71 x 812 ) / 57652
= 71 / 812
= 71
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 497, 355, 812, 639 is 1
