Given numbers are 645, 579, 783, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 579) = 124485
GCD(645, 579) = ( 645 x 579 ) / 124485
= 645 / 579
= 645
Step2:
LCM(3, 783) = 783
GCD(3, 783) = ( 3 x 783 ) / 783
= 3 / 783
= 3
Step3:
LCM(3, 422) = 1266
GCD(3, 422) = ( 3 x 422 ) / 1266
= 3 / 422
= 3
So, Greatest Common Divisor of 645, 579, 783, 422 is 1
