Given numbers are 197, 310, 564, 980
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(197, 310) = 61070
GCD(197, 310) = ( 197 x 310 ) / 61070
= 197 / 310
= 197
Step2:
LCM(1, 564) = 564
GCD(1, 564) = ( 1 x 564 ) / 564
= 1 / 564
= 1
Step3:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
So, Greatest Common Divisor of 197, 310, 564, 980 is 1
