Given numbers are 491, 704, 804, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 704) = 345664
GCD(491, 704) = ( 491 x 704 ) / 345664
= 491 / 704
= 491
Step2:
LCM(1, 804) = 804
GCD(1, 804) = ( 1 x 804 ) / 804
= 1 / 804
= 1
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 491, 704, 804, 665 is 1
