Given numbers are 387, 393, 946, 756

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

Apply this formula for all numbers.

Step1:

LCM(387, 393) = 50697

GCD(387, 393) = ( 387 x 393 ) / 50697

= 387 / 393

= 387

Step2:

LCM(3, 946) = 2838

GCD(3, 946) = ( 3 x 946 ) / 2838

= 3 / 946

= 3

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 387, 393, 946, 756 is 1
