Given numbers are 282, 540, 391, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(282, 540) = 25380
GCD(282, 540) = ( 282 x 540 ) / 25380
= 282 / 540
= 282
Step2:
LCM(6, 391) = 2346
GCD(6, 391) = ( 6 x 391 ) / 2346
= 6 / 391
= 6
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 282, 540, 391, 421 is 1
