Given numbers are 253, 749, 806, 977

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

Apply this formula for all numbers.

Step1:

LCM(253, 749) = 189497

GCD(253, 749) = ( 253 x 749 ) / 189497

= 253 / 749

= 253

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 253, 749, 806, 977 is 1
