Given numbers are 147, 763, 402, 445

The list of prime factors of all numbers are

Prime factors of 147 are 3 x 7 x 7

Prime factors of 763 are 7 x 109

Prime factors of 402 are 2 x 3 x 67

Prime factors of 445 are 5 x 89

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

Given numbers are 147, 763, 402, 445

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

Apply this formula for all numbers.

Step1:

LCM(147, 763) = 16023

GCD(147, 763) = ( 147 x 763 ) / 16023

= 147 / 763

= 147

Step2:

LCM(7, 402) = 2814

GCD(7, 402) = ( 7 x 402 ) / 2814

= 7 / 402

= 7

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 147, 763, 402, 445 is 1
