Given numbers are 815, 763, 646, 474

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

Apply this formula for all numbers.

Step1:

LCM(815, 763) = 621845

GCD(815, 763) = ( 815 x 763 ) / 621845

= 815 / 763

= 815

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 815, 763, 646, 474 is 1
