Given numbers are 100, 128, 402, 445

The list of prime factors of all numbers are

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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 100, 128, 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(100, 128) = 3200

GCD(100, 128) = ( 100 x 128 ) / 3200

= 100 / 128

= 100

Step2:

LCM(4, 402) = 804

GCD(4, 402) = ( 4 x 402 ) / 804

= 4 / 402

= 4

Step3:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

So, Greatest Common Divisor of 100, 128, 402, 445 is 1
