Given numbers are 255, 865, 434, 806
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 865) = 44115
GCD(255, 865) = ( 255 x 865 ) / 44115
= 255 / 865
= 255
Step2:
LCM(5, 434) = 2170
GCD(5, 434) = ( 5 x 434 ) / 2170
= 5 / 434
= 5
Step3:
LCM(1, 806) = 806
GCD(1, 806) = ( 1 x 806 ) / 806
= 1 / 806
= 1
So, Greatest Common Divisor of 255, 865, 434, 806 is 1
