Given numbers are 858, 272, 645, 402

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 645 are 3 x 5 x 43

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 858, 272, 645, 402

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

Apply this formula for all numbers.

Step1:

LCM(858, 272) = 116688

GCD(858, 272) = ( 858 x 272 ) / 116688

= 858 / 272

= 858

Step2:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 858, 272, 645, 402 is 1
