Given numbers are 240, 981, 947, 945
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 981) = 78480
GCD(240, 981) = ( 240 x 981 ) / 78480
= 240 / 981
= 240
Step2:
LCM(3, 947) = 2841
GCD(3, 947) = ( 3 x 947 ) / 2841
= 3 / 947
= 3
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 240, 981, 947, 945 is 1
