Given numbers are 435, 385, 798, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(435, 385) = 33495
GCD(435, 385) = ( 435 x 385 ) / 33495
= 435 / 385
= 435
Step2:
LCM(5, 798) = 3990
GCD(5, 798) = ( 5 x 798 ) / 3990
= 5 / 798
= 5
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 435, 385, 798, 890 is 1
