Given numbers are 318, 878, 974, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(318, 878) = 139602
GCD(318, 878) = ( 318 x 878 ) / 139602
= 318 / 878
= 318
Step2:
LCM(2, 974) = 974
GCD(2, 974) = ( 2 x 974 ) / 974
= 2 / 974
= 2
Step3:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
So, Greatest Common Divisor of 318, 878, 974, 645 is 1
