Given numbers are 649, 130, 857, 863

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(649, 130) = 84370

GCD(649, 130) = ( 649 x 130 ) / 84370

= 649 / 130

= 649

Step2:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 649, 130, 857, 863 is 1
