Given numbers are 550, 420, 882, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 420) = 23100
GCD(550, 420) = ( 550 x 420 ) / 23100
= 550 / 420
= 550
Step2:
LCM(10, 882) = 4410
GCD(10, 882) = ( 10 x 882 ) / 4410
= 10 / 882
= 10
Step3:
LCM(2, 385) = 770
GCD(2, 385) = ( 2 x 385 ) / 770
= 2 / 385
= 2
So, Greatest Common Divisor of 550, 420, 882, 385 is 1
