GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 645) = 66435
GCD(309, 645) = ( 309 x 645 ) / 66435
= 309 / 645
= 309
Step2:
LCM(3, 374) = 1122
GCD(3, 374) = ( 3 x 374 ) / 1122
= 3 / 374
= 3
Step3:
LCM(1, 182) = 182
GCD(1, 182) = ( 1 x 182 ) / 182
= 1 / 182
= 1
So, Greatest Common Divisor of 309, 645, 374, 182 is 1
