Given numbers are 746, 649, 20, 910

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

Apply this formula for all numbers.

Step1:

LCM(746, 649) = 484154

GCD(746, 649) = ( 746 x 649 ) / 484154

= 746 / 649

= 746

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

So, Greatest Common Divisor of 746, 649, 20, 910 is 1
