Given numbers are 247, 221, 46, 977

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

Apply this formula for all numbers.

Step1:

LCM(247, 221) = 4199

GCD(247, 221) = ( 247 x 221 ) / 4199

= 247 / 221

= 247

Step2:

LCM(13, 46) = 598

GCD(13, 46) = ( 13 x 46 ) / 598

= 13 / 46

= 13

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 247, 221, 46, 977 is 1
