Given numbers are 642, 304, 517, 723
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 304) = 97584
GCD(642, 304) = ( 642 x 304 ) / 97584
= 642 / 304
= 642
Step2:
LCM(2, 517) = 1034
GCD(2, 517) = ( 2 x 517 ) / 1034
= 2 / 517
= 2
Step3:
LCM(1, 723) = 723
GCD(1, 723) = ( 1 x 723 ) / 723
= 1 / 723
= 1
So, Greatest Common Divisor of 642, 304, 517, 723 is 1
