Given numbers are 213, 447, 156, 763

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

Prime factors of 447 are 3 x 149

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 763 are 7 x 109

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

Given numbers are 213, 447, 156, 763

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

Apply this formula for all numbers.

Step1:

LCM(213, 447) = 31737

GCD(213, 447) = ( 213 x 447 ) / 31737

= 213 / 447

= 213

Step2:

LCM(3, 156) = 156

GCD(3, 156) = ( 3 x 156 ) / 156

= 3 / 156

= 3

Step3:

LCM(3, 763) = 2289

GCD(3, 763) = ( 3 x 763 ) / 2289

= 3 / 763

= 3

So, Greatest Common Divisor of 213, 447, 156, 763 is 1
