Given numbers are 763, 487, 690, 220

The list of prime factors of all numbers are

Prime factors of 763 are 7 x 109

Prime factors of 487 are 487

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 220 are 2 x 2 x 5 x 11

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 763, 487, 690, 220

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

Apply this formula for all numbers.

Step1:

LCM(763, 487) = 371581

GCD(763, 487) = ( 763 x 487 ) / 371581

= 763 / 487

= 763

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 763, 487, 690, 220 is 1
