Given numbers are 801, 817, 640
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(801, 817) = 654417
GCD(801, 817) = ( 801 x 817 ) / 654417
= 801 / 817
= 801
Step2:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 801, 817, 640 is 1
