Given numbers are 924,628,392,718
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 924,628,392,718 is 729111768.
Find LCM of 924,628,392,718 with Prime Factorization
| 2 | 924, 628, 392, 718 |
| 2 | 462, 314, 196, 359 |
| 7 | 231, 157, 98, 359 |
| 33, 157, 14, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 33 x 157 x 14 x 359 = 729111768
Therefore, the lowest common multiple of 924,628,392,718 is 729111768.
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.
924 x 628 x 392 x 718 = 163321036032
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.
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
628 : 1, 2, 4, 157, 314, 628
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
718 : 1, 2, 359, 718
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,628,392,718, is 2.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
628:2x 2x 157
392:2x 2x 2x 7x 7
718:2x 359
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 7 = 112
Therefore, the value for common factors is 112.
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 = 163321036032/(2x112)
LCM = 163321036032/224
LCM = 729111768
Thus, we can understand that the LCM of 924,628,392,718 is 729111768.
