Given numbers are 649, 230, 911, 688

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

Apply this formula for all numbers.

Step1:

LCM(649, 230) = 149270

GCD(649, 230) = ( 649 x 230 ) / 149270

= 649 / 230

= 649

Step2:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 649, 230, 911, 688 is 1
