Given numbers are 146, 630, 757, 420

The list of prime factors of all numbers are

Prime factors of 146 are 2 x 73

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 757 are 757

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 146, 630, 757, 420

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

Apply this formula for all numbers.

Step1:

LCM(146, 630) = 45990

GCD(146, 630) = ( 146 x 630 ) / 45990

= 146 / 630

= 146

Step2:

LCM(2, 757) = 1514

GCD(2, 757) = ( 2 x 757 ) / 1514

= 2 / 757

= 2

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 146, 630, 757, 420 is 1
