Given numbers are 678, 490, 167, 981

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

Apply this formula for all numbers.

Step1:

LCM(678, 490) = 166110

GCD(678, 490) = ( 678 x 490 ) / 166110

= 678 / 490

= 678

Step2:

LCM(2, 167) = 334

GCD(2, 167) = ( 2 x 167 ) / 334

= 2 / 167

= 2

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 678, 490, 167, 981 is 1
