Given numbers are 281, 408, 221, 570
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(281, 408) = 114648
GCD(281, 408) = ( 281 x 408 ) / 114648
= 281 / 408
= 281
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
= 1 / 570
= 1
So, Greatest Common Divisor of 281, 408, 221, 570 is 1
