Given numbers are 282, 561, 402, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(282, 561) = 52734
GCD(282, 561) = ( 282 x 561 ) / 52734
= 282 / 561
= 282
Step2:
LCM(3, 402) = 402
GCD(3, 402) = ( 3 x 402 ) / 402
= 3 / 402
= 3
Step3:
LCM(3, 409) = 1227
GCD(3, 409) = ( 3 x 409 ) / 1227
= 3 / 409
= 3
So, Greatest Common Divisor of 282, 561, 402, 409 is 1
