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, 120) = 29640
GCD(247, 120) = ( 247 x 120 ) / 29640
= 247 / 120
= 247
Step3:
LCM(1, 442) = 442
GCD(1, 442) = ( 1 x 442 ) / 442
= 1 / 442
= 1
So, Greatest Common Divisor of 247, 988, 120, 442 is 1
