Given numbers are 645, 297, 237, 388
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 297) = 63855
GCD(645, 297) = ( 645 x 297 ) / 63855
= 645 / 297
= 645
Step2:
LCM(3, 237) = 237
GCD(3, 237) = ( 3 x 237 ) / 237
= 3 / 237
= 3
Step3:
LCM(3, 388) = 1164
GCD(3, 388) = ( 3 x 388 ) / 1164
= 3 / 388
= 3
So, Greatest Common Divisor of 645, 297, 237, 388 is 1
