Given numbers are 109, 678, 248, 988

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

Apply this formula for all numbers.

Step1:

LCM(109, 678) = 73902

GCD(109, 678) = ( 109 x 678 ) / 73902

= 109 / 678

= 109

Step2:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

Step3:

LCM(1, 988) = 988

GCD(1, 988) = ( 1 x 988 ) / 988

= 1 / 988

= 1

So, Greatest Common Divisor of 109, 678, 248, 988 is 1
