Given numbers are 855, 673, 247, 844
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 673) = 575415
GCD(855, 673) = ( 855 x 673 ) / 575415
= 855 / 673
= 855
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 844) = 844
GCD(1, 844) = ( 1 x 844 ) / 844
= 1 / 844
= 1
So, Greatest Common Divisor of 855, 673, 247, 844 is 1
