Given numbers are 387, 153, 844, 845

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

Apply this formula for all numbers.

Step1:

LCM(387, 153) = 6579

GCD(387, 153) = ( 387 x 153 ) / 6579

= 387 / 153

= 387

Step2:

LCM(9, 844) = 7596

GCD(9, 844) = ( 9 x 844 ) / 7596

= 9 / 844

= 9

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 387, 153, 844, 845 is 1
