Given numbers are 980, 359, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 359) = 351820
GCD(980, 359) = ( 980 x 359 ) / 351820
= 980 / 359
= 980
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 980, 359, 145 is 1
