Given numbers are 215, 690, 748, 463

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

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

Prime factors of 748 are 2 x 2 x 11 x 17

Prime factors of 463 are 463

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

Given numbers are 215, 690, 748, 463

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

Apply this formula for all numbers.

Step1:

LCM(215, 690) = 29670

GCD(215, 690) = ( 215 x 690 ) / 29670

= 215 / 690

= 215

Step2:

LCM(5, 748) = 3740

GCD(5, 748) = ( 5 x 748 ) / 3740

= 5 / 748

= 5

Step3:

LCM(1, 463) = 463

GCD(1, 463) = ( 1 x 463 ) / 463

= 1 / 463

= 1

So, Greatest Common Divisor of 215, 690, 748, 463 is 1
