Given numbers are 552, 120, 441, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(552, 120) = 2760
GCD(552, 120) = ( 552 x 120 ) / 2760
= 552 / 120
= 552
Step2:
LCM(24, 441) = 3528
GCD(24, 441) = ( 24 x 441 ) / 3528
= 24 / 441
= 24
Step3:
LCM(3, 391) = 1173
GCD(3, 391) = ( 3 x 391 ) / 1173
= 3 / 391
= 3
So, Greatest Common Divisor of 552, 120, 441, 391 is 1
