Given numbers are 697, 636, 721, 647

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

Apply this formula for all numbers.

Step1:

LCM(697, 636) = 443292

GCD(697, 636) = ( 697 x 636 ) / 443292

= 697 / 636

= 697

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 697, 636, 721, 647 is 1
