GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 328) = 211560
GCD(645, 328) = ( 645 x 328 ) / 211560
= 645 / 328
= 645
Step2:
LCM(1, 544) = 544
GCD(1, 544) = ( 1 x 544 ) / 544
= 1 / 544
= 1
Step3:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
So, Greatest Common Divisor of 645, 328, 544, 853 is 1
