Given numbers are 385, 340, 140, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 340) = 26180
GCD(385, 340) = ( 385 x 340 ) / 26180
= 385 / 340
= 385
Step2:
LCM(5, 140) = 140
GCD(5, 140) = ( 5 x 140 ) / 140
= 5 / 140
= 5
Step3:
LCM(5, 438) = 2190
GCD(5, 438) = ( 5 x 438 ) / 2190
= 5 / 438
= 5
So, Greatest Common Divisor of 385, 340, 140, 438 is 1
