Given numbers are 441, 920, 647, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 920) = 405720
GCD(441, 920) = ( 441 x 920 ) / 405720
= 441 / 920
= 441
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 441, 920, 647, 223 is 1
