Given numbers are 649, 346, 851, 130
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 346) = 224554
GCD(649, 346) = ( 649 x 346 ) / 224554
= 649 / 346
= 649
Step2:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
Step3:
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
= 1 / 130
= 1
So, Greatest Common Divisor of 649, 346, 851, 130 is 1
