Given numbers are 812, 618, 845, 402

The list of prime factors of all numbers are

Prime factors of 812 are 2 x 2 x 7 x 29

Prime factors of 618 are 2 x 3 x 103

Prime factors of 845 are 5 x 13 x 13

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 812, 618, 845, 402

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

Apply this formula for all numbers.

Step1:

LCM(812, 618) = 250908

GCD(812, 618) = ( 812 x 618 ) / 250908

= 812 / 618

= 812

Step2:

LCM(2, 845) = 1690

GCD(2, 845) = ( 2 x 845 ) / 1690

= 2 / 845

= 2

Step3:

LCM(1, 402) = 402

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

= 1 / 402

= 1

So, Greatest Common Divisor of 812, 618, 845, 402 is 1
