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

Apply this formula for all numbers.

Step1:

LCM(247, 988) = 988

GCD(247, 988) = ( 247 x 988 ) / 988

= 247 / 988

= 247

Step2:

LCM(247, 921) = 227487

GCD(247, 921) = ( 247 x 921 ) / 227487

= 247 / 921

= 247

Step3:

LCM(1, 369) = 369

GCD(1, 369) = ( 1 x 369 ) / 369

= 1 / 369

= 1

So, Greatest Common Divisor of 247, 988, 921, 369 is 1
