Given numbers are 861, 201, 673, 378

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

Apply this formula for all numbers.

Step1:

LCM(861, 201) = 57687

GCD(861, 201) = ( 861 x 201 ) / 57687

= 861 / 201

= 861

Step2:

LCM(3, 673) = 2019

GCD(3, 673) = ( 3 x 673 ) / 2019

= 3 / 673

= 3

Step3:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

So, Greatest Common Divisor of 861, 201, 673, 378 is 1
