Given numbers are 690,709,663,493,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,709,663,493,648 is 338617464120.
Find LCM of 690,709,663,493,648 with Prime Factorization
| 2 | 690, 709, 663, 493, 648 |
| 3 | 345, 709, 663, 493, 324 |
| 17 | 115, 709, 221, 493, 108 |
| 115, 709, 13, 29, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 115 x 709 x 13 x 29 x 108 = 338617464120
Therefore, the lowest common multiple of 690,709,663,493,648 is 338617464120.
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.
690 x 709 x 663 x 493 x 648 = 103616944020720
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
709 : 1, 709
663 : 1, 3, 13, 17, 39, 51, 221, 663
493 : 1, 17, 29, 493
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,709,663,493,648, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
709:709
663:3x 13x 17
493:17x 29
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 103616944020720/(1x306)
LCM = 103616944020720/306
LCM = 338617464120
Thus, we can understand that the LCM of 690,709,663,493,648 is 338617464120.
