Given numbers are 220, 289, 411, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 289) = 63580
GCD(220, 289) = ( 220 x 289 ) / 63580
= 220 / 289
= 220
Step2:
LCM(1, 411) = 411
GCD(1, 411) = ( 1 x 411 ) / 411
= 1 / 411
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 220, 289, 411, 515 is 1
