Given numbers are 129, 505, 980, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 505) = 65145
GCD(129, 505) = ( 129 x 505 ) / 65145
= 129 / 505
= 129
Step2:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 129, 505, 980, 143 is 1
