Given numbers are 153, 830, 840, 879

The list of prime factors of all numbers are

Prime factors of 153 are 3 x 3 x 17

Prime factors of 830 are 2 x 5 x 83

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

Prime factors of 879 are 3 x 293

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

Given numbers are 153, 830, 840, 879

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

Apply this formula for all numbers.

Step1:

LCM(153, 830) = 126990

GCD(153, 830) = ( 153 x 830 ) / 126990

= 153 / 830

= 153

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 879) = 879

GCD(1, 879) = ( 1 x 879 ) / 879

= 1 / 879

= 1

So, Greatest Common Divisor of 153, 830, 840, 879 is 1
