Given numbers are 280, 661, 289, 222
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 661) = 185080
GCD(280, 661) = ( 280 x 661 ) / 185080
= 280 / 661
= 280
Step2:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
Step3:
LCM(1, 222) = 222
GCD(1, 222) = ( 1 x 222 ) / 222
= 1 / 222
= 1
So, Greatest Common Divisor of 280, 661, 289, 222 is 1
