Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 3 x 11 x 1 x 1 x 17 x 7 x 1 = 1272348
Therefore, the lowest common multiple of 972,486,918,924,891 is 1272348.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
972 x 486 x 918 x 924 x 891 = 357021927751104
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,486,918,924,891, is 3.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
486:2x 3x 3x 3x 3x 3
918:2x 3x 3x 3x 17
924:2x 2x 3x 7x 11
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 3x 3x 3x 3x 3x 3x 3x 3x 3x 3x 11 = 93533616
Therefore, the value for common factors is 93533616.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 357021927751104/(3x93533616)
LCM = 357021927751104/280600848
LCM = 1272348
Thus, we can understand that the LCM of 972,486,918,924,891 is 1272348.
