The LCM of 309,924,748,653 is 1056504372.
Find LCM of 309,924,748,653 with Prime Factorization
| 2 | 309, 924, 748, 653 |
| 2 | 309, 462, 374, 653 |
| 3 | 309, 231, 187, 653 |
| 11 | 103, 77, 187, 653 |
| 103, 7, 17, 653 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 103 x 7 x 17 x 653 = 1056504372
Therefore, the lowest common multiple of 309,924,748,653 is 1056504372.
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.
309 x 924 x 748 x 653 = 139458577104
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.
309 : 1, 3, 103, 309
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
653 : 1, 653
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,924,748,653, is 1.
Now, the common factors can be found like this.
309:3x 103
924:2x 2x 3x 7x 11
748:2x 2x 11x 17
653:653
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 139458577104/(1x132)
LCM = 139458577104/132
LCM = 1056504372
Thus, we can understand that the LCM of 309,924,748,653 is 1056504372.
