Given numbers are 643, 469, 627, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 469) = 301567
GCD(643, 469) = ( 643 x 469 ) / 301567
= 643 / 469
= 643
Step2:
LCM(1, 627) = 627
GCD(1, 627) = ( 1 x 627 ) / 627
= 1 / 627
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 643, 469, 627, 515 is 1
