Given numbers are 545, 402, 870, 628

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 402 are 2 x 3 x 67

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 628 are 2 x 2 x 157

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

Given numbers are 545, 402, 870, 628

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

Apply this formula for all numbers.

Step1:

LCM(545, 402) = 219090

GCD(545, 402) = ( 545 x 402 ) / 219090

= 545 / 402

= 545

Step2:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 545, 402, 870, 628 is 1
