Given numbers are 743,318,484,605,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 743,318,484,605,553 is 158098021620.
Find LCM of 743,318,484,605,553 with Prime Factorization
| 2 | 743, 318, 484, 605, 553 |
| 11 | 743, 159, 242, 605, 553 |
| 11 | 743, 159, 22, 55, 553 |
| 743, 159, 2, 5, 553 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 743 x 159 x 2 x 5 x 553 = 158098021620
Therefore, the lowest common multiple of 743,318,484,605,553 is 158098021620.
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.
743 x 318 x 484 x 605 x 553 = 38259721232040
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.
743 : 1, 743
318 : 1, 2, 3, 6, 53, 106, 159, 318
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
605 : 1, 5, 11, 55, 121, 605
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,318,484,605,553, is 1.
Now, the common factors can be found like this.
743:743
318:2x 3x 53
484:2x 2x 11x 11
605:5x 11x 11
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 38259721232040/(1x242)
LCM = 38259721232040/242
LCM = 158098021620
Thus, we can understand that the LCM of 743,318,484,605,553 is 158098021620.
