Given numbers are 942, 309, 980, 207
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(942, 309) = 97026
GCD(942, 309) = ( 942 x 309 ) / 97026
= 942 / 309
= 942
Step2:
LCM(3, 980) = 2940
GCD(3, 980) = ( 3 x 980 ) / 2940
= 3 / 980
= 3
Step3:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
So, Greatest Common Divisor of 942, 309, 980, 207 is 1
