Given numbers are 856, 478, 581, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(856, 478) = 204584
GCD(856, 478) = ( 856 x 478 ) / 204584
= 856 / 478
= 856
Step2:
LCM(2, 581) = 1162
GCD(2, 581) = ( 2 x 581 ) / 1162
= 2 / 581
= 2
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 856, 478, 581, 159 is 1
