GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 717) = 706245
GCD(985, 717) = ( 985 x 717 ) / 706245
= 985 / 717
= 985
Step2:
LCM(1, 919) = 919
GCD(1, 919) = ( 1 x 919 ) / 919
= 1 / 919
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 985, 717, 919, 638 is 1
