Given numbers are 945, 453, 562, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 453) = 142695
GCD(945, 453) = ( 945 x 453 ) / 142695
= 945 / 453
= 945
Step2:
LCM(3, 562) = 1686
GCD(3, 562) = ( 3 x 562 ) / 1686
= 3 / 562
= 3
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 945, 453, 562, 309 is 1
