Given numbers are 408, 220, 807, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 220) = 22440
GCD(408, 220) = ( 408 x 220 ) / 22440
= 408 / 220
= 408
Step2:
LCM(4, 807) = 3228
GCD(4, 807) = ( 4 x 807 ) / 3228
= 4 / 807
= 4
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 408, 220, 807, 120 is 1
