Given numbers are 384, 390, 442, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(384, 390) = 24960
GCD(384, 390) = ( 384 x 390 ) / 24960
= 384 / 390
= 384
Step2:
LCM(6, 442) = 1326
GCD(6, 442) = ( 6 x 442 ) / 1326
= 6 / 442
= 6
Step3:
LCM(2, 655) = 1310
GCD(2, 655) = ( 2 x 655 ) / 1310
= 2 / 655
= 2
So, Greatest Common Divisor of 384, 390, 442, 655 is 1
