Given numbers are 645, 655, 931, 293
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 655) = 84495
GCD(645, 655) = ( 645 x 655 ) / 84495
= 645 / 655
= 645
Step2:
LCM(5, 931) = 4655
GCD(5, 931) = ( 5 x 931 ) / 4655
= 5 / 931
= 5
Step3:
LCM(1, 293) = 293
GCD(1, 293) = ( 1 x 293 ) / 293
= 1 / 293
= 1
So, Greatest Common Divisor of 645, 655, 931, 293 is 1
