GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(248, 370) = 45880
GCD(248, 370) = ( 248 x 370 ) / 45880
= 248 / 370
= 248
Step2:
LCM(2, 912) = 912
GCD(2, 912) = ( 2 x 912 ) / 912
= 2 / 912
= 2
Step3:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
So, Greatest Common Divisor of 248, 370, 912, 645 is 1
