Given numbers are 840, 578, 799, 666

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 578 are 2 x 17 x 17

Prime factors of 799 are 17 x 47

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 840, 578, 799, 666

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

Apply this formula for all numbers.

Step1:

LCM(840, 578) = 242760

GCD(840, 578) = ( 840 x 578 ) / 242760

= 840 / 578

= 840

Step2:

LCM(2, 799) = 1598

GCD(2, 799) = ( 2 x 799 ) / 1598

= 2 / 799

= 2

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 840, 578, 799, 666 is 1
