Given numbers are 420, 383, 281, 555
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 383) = 160860
GCD(420, 383) = ( 420 x 383 ) / 160860
= 420 / 383
= 420
Step2:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
Step3:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
So, Greatest Common Divisor of 420, 383, 281, 555 is 1
