Given numbers are 385, 255, 988, 760
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 255) = 19635
GCD(385, 255) = ( 385 x 255 ) / 19635
= 385 / 255
= 385
Step2:
LCM(5, 988) = 4940
GCD(5, 988) = ( 5 x 988 ) / 4940
= 5 / 988
= 5
Step3:
LCM(1, 760) = 760
GCD(1, 760) = ( 1 x 760 ) / 760
= 1 / 760
= 1
So, Greatest Common Divisor of 385, 255, 988, 760 is 1
