The list of prime factors of all numbers are

Prime factors of 619 are 619

Prime factors of 970 are 2 x 5 x 97

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

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 619, 970, 690, 144

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

Apply this formula for all numbers.

Step1:

LCM(619, 970) = 600430

GCD(619, 970) = ( 619 x 970 ) / 600430

= 619 / 970

= 619

Step2:

LCM(1, 690) = 690

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

= 1 / 690

= 1

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 619, 970, 690, 144 is 1
