Given numbers are 446, 442, 720, 553
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(446, 442) = 98566
GCD(446, 442) = ( 446 x 442 ) / 98566
= 446 / 442
= 446
Step2:
LCM(2, 720) = 720
GCD(2, 720) = ( 2 x 720 ) / 720
= 2 / 720
= 2
Step3:
LCM(2, 553) = 1106
GCD(2, 553) = ( 2 x 553 ) / 1106
= 2 / 553
= 2
So, Greatest Common Divisor of 446, 442, 720, 553 is 1
