Given numbers are 685, 426, 631, 925
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 426) = 291810
GCD(685, 426) = ( 685 x 426 ) / 291810
= 685 / 426
= 685
Step2:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
Step3:
LCM(1, 925) = 925
GCD(1, 925) = ( 1 x 925 ) / 925
= 1 / 925
= 1
So, Greatest Common Divisor of 685, 426, 631, 925 is 1
