Given numbers are 868, 791, 784, 478

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

Apply this formula for all numbers.

Step1:

LCM(868, 791) = 98084

GCD(868, 791) = ( 868 x 791 ) / 98084

= 868 / 791

= 868

Step2:

LCM(7, 784) = 784

GCD(7, 784) = ( 7 x 784 ) / 784

= 7 / 784

= 7

Step3:

LCM(7, 478) = 3346

GCD(7, 478) = ( 7 x 478 ) / 3346

= 7 / 478

= 7

So, Greatest Common Divisor of 868, 791, 784, 478 is 1
