Given numbers are 473, 645, 307, 653
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(473, 645) = 7095
GCD(473, 645) = ( 473 x 645 ) / 7095
= 473 / 645
= 473
Step2:
LCM(43, 307) = 13201
GCD(43, 307) = ( 43 x 307 ) / 13201
= 43 / 307
= 43
Step3:
LCM(1, 653) = 653
GCD(1, 653) = ( 1 x 653 ) / 653
= 1 / 653
= 1
So, Greatest Common Divisor of 473, 645, 307, 653 is 1
