Given numbers are 855, 321, 442, 550
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 321) = 91485
GCD(855, 321) = ( 855 x 321 ) / 91485
= 855 / 321
= 855
Step2:
LCM(3, 442) = 1326
GCD(3, 442) = ( 3 x 442 ) / 1326
= 3 / 442
= 3
Step3:
LCM(1, 550) = 550
GCD(1, 550) = ( 1 x 550 ) / 550
= 1 / 550
= 1
So, Greatest Common Divisor of 855, 321, 442, 550 is 1
