Given numbers are 804, 638, 480, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(804, 638) = 256476
GCD(804, 638) = ( 804 x 638 ) / 256476
= 804 / 638
= 804
Step2:
LCM(2, 480) = 480
GCD(2, 480) = ( 2 x 480 ) / 480
= 2 / 480
= 2
Step3:
LCM(2, 155) = 310
GCD(2, 155) = ( 2 x 155 ) / 310
= 2 / 155
= 2
So, Greatest Common Divisor of 804, 638, 480, 155 is 1
