Given numbers are 640, 180, 806, 893
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 180) = 5760
GCD(640, 180) = ( 640 x 180 ) / 5760
= 640 / 180
= 640
Step2:
LCM(20, 806) = 8060
GCD(20, 806) = ( 20 x 806 ) / 8060
= 20 / 806
= 20
Step3:
LCM(2, 893) = 1786
GCD(2, 893) = ( 2 x 893 ) / 1786
= 2 / 893
= 2
So, Greatest Common Divisor of 640, 180, 806, 893 is 1
