Given numbers are 520, 155, 806, 395
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(520, 155) = 16120
GCD(520, 155) = ( 520 x 155 ) / 16120
= 520 / 155
= 520
Step2:
LCM(5, 806) = 4030
GCD(5, 806) = ( 5 x 806 ) / 4030
= 5 / 806
= 5
Step3:
LCM(1, 395) = 395
GCD(1, 395) = ( 1 x 395 ) / 395
= 1 / 395
= 1
So, Greatest Common Divisor of 520, 155, 806, 395 is 1
