Given numbers are 578, 384, 308, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(578, 384) = 110976
GCD(578, 384) = ( 578 x 384 ) / 110976
= 578 / 384
= 578
Step2:
LCM(2, 308) = 308
GCD(2, 308) = ( 2 x 308 ) / 308
= 2 / 308
= 2
Step3:
LCM(2, 155) = 310
GCD(2, 155) = ( 2 x 155 ) / 310
= 2 / 155
= 2
So, Greatest Common Divisor of 578, 384, 308, 155 is 1
