Given numbers are 755, 716, 644, 156

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 716 are 2 x 2 x 179

Prime factors of 644 are 2 x 2 x 7 x 23

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

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

Given numbers are 755, 716, 644, 156

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

Apply this formula for all numbers.

Step1:

LCM(755, 716) = 540580

GCD(755, 716) = ( 755 x 716 ) / 540580

= 755 / 716

= 755

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 755, 716, 644, 156 is 1
