Given numbers are 282, 456, 493, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(282, 456) = 21432
GCD(282, 456) = ( 282 x 456 ) / 21432
= 282 / 456
= 282
Step2:
LCM(6, 493) = 2958
GCD(6, 493) = ( 6 x 493 ) / 2958
= 6 / 493
= 6
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 282, 456, 493, 420 is 1
