Given numbers are 290, 239, 260, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 239) = 69310
GCD(290, 239) = ( 290 x 239 ) / 69310
= 290 / 239
= 290
Step2:
LCM(1, 260) = 260
GCD(1, 260) = ( 1 x 260 ) / 260
= 1 / 260
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 290, 239, 260, 142 is 1
