Given numbers are 830, 666, 742, 387

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

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

Prime factors of 742 are 2 x 7 x 53

Prime factors of 387 are 3 x 3 x 43

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

Given numbers are 830, 666, 742, 387

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

Apply this formula for all numbers.

Step1:

LCM(830, 666) = 276390

GCD(830, 666) = ( 830 x 666 ) / 276390

= 830 / 666

= 830

Step2:

LCM(2, 742) = 742

GCD(2, 742) = ( 2 x 742 ) / 742

= 2 / 742

= 2

Step3:

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

= 2 / 387

= 2

So, Greatest Common Divisor of 830, 666, 742, 387 is 1
