Given numbers are 742, 510, 645, 979
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 510) = 189210
GCD(742, 510) = ( 742 x 510 ) / 189210
= 742 / 510
= 742
Step2:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
Step3:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
So, Greatest Common Divisor of 742, 510, 645, 979 is 1
