Given numbers are 805, 124, 508, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 124) = 99820
GCD(805, 124) = ( 805 x 124 ) / 99820
= 805 / 124
= 805
Step2:
LCM(1, 508) = 508
GCD(1, 508) = ( 1 x 508 ) / 508
= 1 / 508
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 805, 124, 508, 220 is 1
