Given numbers are 945, 823, 409, 387

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

Apply this formula for all numbers.

Step1:

LCM(945, 823) = 777735

GCD(945, 823) = ( 945 x 823 ) / 777735

= 945 / 823

= 945

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 387) = 387

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

= 1 / 387

= 1

So, Greatest Common Divisor of 945, 823, 409, 387 is 1
