Given numbers are 644, 456, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 456) = 73416
GCD(644, 456) = ( 644 x 456 ) / 73416
= 644 / 456
= 644
Step2:
LCM(4, 807) = 3228
GCD(4, 807) = ( 4 x 807 ) / 3228
= 4 / 807
= 4
So, Greatest Common Divisor of 644, 456, 807 is 1
