Given numbers are 636,900,742,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,900,742,553 is 26378100.
Find LCM of 636,900,742,553 with Prime Factorization
| 2 | 636, 900, 742, 553 |
| 2 | 318, 450, 371, 553 |
| 3 | 159, 225, 371, 553 |
| 7 | 53, 75, 371, 553 |
| 53 | 53, 75, 53, 79 |
| 1, 75, 1, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 53 x 1 x 75 x 1 x 79 = 26378100
Therefore, the lowest common multiple of 636,900,742,553 is 26378100.
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.
636 x 900 x 742 x 553 = 234870602400
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
742 : 1, 2, 7, 14, 53, 106, 371, 742
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,900,742,553, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
900:2x 2x 3x 3x 5x 5
742:2x 7x 53
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 2x 2x 3x 7x 53 = 8904
Therefore, the value for common factors is 8904.
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 = 234870602400/(1x8904)
LCM = 234870602400/8904
LCM = 26378100
Thus, we can understand that the LCM of 636,900,742,553 is 26378100.
