Given numbers are 237, 645, 138, 452
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(237, 645) = 50955
GCD(237, 645) = ( 237 x 645 ) / 50955
= 237 / 645
= 237
Step2:
LCM(3, 138) = 138
GCD(3, 138) = ( 3 x 138 ) / 138
= 3 / 138
= 3
Step3:
LCM(3, 452) = 1356
GCD(3, 452) = ( 3 x 452 ) / 1356
= 3 / 452
= 3
So, Greatest Common Divisor of 237, 645, 138, 452 is 1
