Find LCM of 972,918,620,552,693 with Prime Factorization
| 2 | 972, 918, 620, 552, 693 |
| 2 | 486, 459, 310, 276, 693 |
| 3 | 243, 459, 155, 138, 693 |
| 3 | 81, 153, 155, 46, 231 |
| 3 | 27, 51, 155, 46, 77 |
| 9, 17, 155, 46, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 9 x 17 x 155 x 46 x 77 = 9071841240
Therefore, the lowest common multiple of 972,918,620,552,693 is 9071841240.
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 918 x 620 x 552 x 693 = 211627912446720
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
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,918,620,552,693, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
918:2x 3x 3x 3x 17
620:2x 2x 5x 31
552:2x 2x 2x 3x 23
693:3x 3x 7x 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 2x 3x 3x 3x 3x 3x 3 = 23328
Therefore, the value for common factors is 23328.
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 = 211627912446720/(1x23328)
LCM = 211627912446720/23328
LCM = 9071841240
Thus, we can understand that the LCM of 972,918,620,552,693 is 9071841240.
