Given numbers are 555, 220, 447, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(555, 220) = 24420
GCD(555, 220) = ( 555 x 220 ) / 24420
= 555 / 220
= 555
Step2:
LCM(5, 447) = 2235
GCD(5, 447) = ( 5 x 447 ) / 2235
= 5 / 447
= 5
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 555, 220, 447, 417 is 1
