Given numbers are 858, 378, 660, 611

The list of prime factors of all numbers are

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

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 611 are 13 x 47

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

Given numbers are 858, 378, 660, 611

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

Apply this formula for all numbers.

Step1:

LCM(858, 378) = 54054

GCD(858, 378) = ( 858 x 378 ) / 54054

= 858 / 378

= 858

Step2:

LCM(6, 660) = 660

GCD(6, 660) = ( 6 x 660 ) / 660

= 6 / 660

= 6

Step3:

LCM(6, 611) = 3666

GCD(6, 611) = ( 6 x 611 ) / 3666

= 6 / 611

= 6

So, Greatest Common Divisor of 858, 378, 660, 611 is 1
