Given numbers are 123, 615, 948, 986

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

Apply this formula for all numbers.

Step1:

LCM(123, 615) = 615

GCD(123, 615) = ( 123 x 615 ) / 615

= 123 / 615

= 123

Step2:

LCM(123, 948) = 38868

GCD(123, 948) = ( 123 x 948 ) / 38868

= 123 / 948

= 123

Step3:

LCM(3, 986) = 2958

GCD(3, 986) = ( 3 x 986 ) / 2958

= 3 / 986

= 3

So, Greatest Common Divisor of 123, 615, 948, 986 is 1
