Given numbers are 678, 661, 862, 313

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

Apply this formula for all numbers.

Step1:

LCM(678, 661) = 448158

GCD(678, 661) = ( 678 x 661 ) / 448158

= 678 / 661

= 678

Step2:

LCM(1, 862) = 862

GCD(1, 862) = ( 1 x 862 ) / 862

= 1 / 862

= 1

Step3:

LCM(1, 313) = 313

GCD(1, 313) = ( 1 x 313 ) / 313

= 1 / 313

= 1

So, Greatest Common Divisor of 678, 661, 862, 313 is 1
