GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 897) = 34086
GCD(494, 897) = ( 494 x 897 ) / 34086
= 494 / 897
= 494
Step2:
LCM(13, 638) = 8294
GCD(13, 638) = ( 13 x 638 ) / 8294
= 13 / 638
= 13
Step3:
LCM(1, 957) = 957
GCD(1, 957) = ( 1 x 957 ) / 957
= 1 / 957
= 1
So, Greatest Common Divisor of 494, 897, 638, 957 is 1
