Given numbers are 349, 678, 387, 915

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

Apply this formula for all numbers.

Step1:

LCM(349, 678) = 236622

GCD(349, 678) = ( 349 x 678 ) / 236622

= 349 / 678

= 349

Step2:

LCM(1, 387) = 387

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

= 1 / 387

= 1

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 349, 678, 387, 915 is 1
