Given numbers are 645, 316, 162, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 316) = 203820
GCD(645, 316) = ( 645 x 316 ) / 203820
= 645 / 316
= 645
Step2:
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
= 1 / 162
= 1
Step3:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
So, Greatest Common Divisor of 645, 316, 162, 427 is 1
