Find LCM of 553,680,959,918,490 with Prime Factorization
| 2 | 553, 680, 959, 918, 490 |
| 5 | 553, 340, 959, 459, 245 |
| 7 | 553, 68, 959, 459, 49 |
| 17 | 79, 68, 137, 459, 7 |
| 79, 4, 137, 27, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 17 x 79 x 4 x 137 x 27 x 7 = 9736803720
Therefore, the lowest common multiple of 553,680,959,918,490 is 9736803720.
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.
553 x 680 x 959 x 918 x 490 = 162215149975200
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.
553 : 1, 7, 79, 553
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
959 : 1, 7, 137, 959
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,680,959,918,490, is 1.
Now, the common factors can be found like this.
553:7x 79
680:2x 2x 2x 5x 17
959:7x 137
918:2x 3x 3x 3x 17
490:2x 5x 7x 7
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 5x 7x 7x 17 = 16660
Therefore, the value for common factors is 16660.
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 = 162215149975200/(1x16660)
LCM = 162215149975200/16660
LCM = 9736803720
Thus, we can understand that the LCM of 553,680,959,918,490 is 9736803720.
