GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 688) = 264880
GCD(385, 688) = ( 385 x 688 ) / 264880
= 385 / 688
= 385
Step2:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
Step3:
LCM(1, 240) = 240
GCD(1, 240) = ( 1 x 240 ) / 240
= 1 / 240
= 1
So, Greatest Common Divisor of 385, 688, 989, 240 is 1
