Given numbers are 108, 645, 979, 320
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(108, 645) = 23220
GCD(108, 645) = ( 108 x 645 ) / 23220
= 108 / 645
= 108
Step2:
LCM(3, 979) = 2937
GCD(3, 979) = ( 3 x 979 ) / 2937
= 3 / 979
= 3
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 108, 645, 979, 320 is 1
