Given numbers are 688, 649, 811, 958
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 649) = 446512
GCD(688, 649) = ( 688 x 649 ) / 446512
= 688 / 649
= 688
Step2:
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
= 1 / 811
= 1
Step3:
LCM(1, 958) = 958
GCD(1, 958) = ( 1 x 958 ) / 958
= 1 / 958
= 1
So, Greatest Common Divisor of 688, 649, 811, 958 is 1
