Given numbers are 247, 227, 787, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 227) = 56069
GCD(247, 227) = ( 247 x 227 ) / 56069
= 247 / 227
= 247
Step2:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 247, 227, 787, 556 is 1
