GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 689) = 561535
GCD(815, 689) = ( 815 x 689 ) / 561535
= 815 / 689
= 815
Step2:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
Step3:
LCM(1, 953) = 953
GCD(1, 953) = ( 1 x 953 ) / 953
= 1 / 953
= 1
So, Greatest Common Divisor of 815, 689, 426, 953 is 1
