Given numbers are 751, 402, 545, 645

The list of prime factors of all numbers are

Prime factors of 751 are 751

Prime factors of 402 are 2 x 3 x 67

Prime factors of 545 are 5 x 109

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 751, 402, 545, 645

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

Apply this formula for all numbers.

Step1:

LCM(751, 402) = 301902

GCD(751, 402) = ( 751 x 402 ) / 301902

= 751 / 402

= 751

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 751, 402, 545, 645 is 1
