Given numbers are 604, 140, 687, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(604, 140) = 21140
GCD(604, 140) = ( 604 x 140 ) / 21140
= 604 / 140
= 604
Step2:
LCM(4, 687) = 2748
GCD(4, 687) = ( 4 x 687 ) / 2748
= 4 / 687
= 4
Step3:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
So, Greatest Common Divisor of 604, 140, 687, 985 is 1
