Given numbers are 378, 705, 665, 387

The list of prime factors of all numbers are

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

Prime factors of 705 are 3 x 5 x 47

Prime factors of 665 are 5 x 7 x 19

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 378, 705, 665, 387

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

Apply this formula for all numbers.

Step1:

LCM(378, 705) = 88830

GCD(378, 705) = ( 378 x 705 ) / 88830

= 378 / 705

= 378

Step2:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 378, 705, 665, 387 is 1
