Given numbers are 810,616,624,253
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 810,616,624,253 is 149189040.
Find LCM of 810,616,624,253 with Prime Factorization
| 2 | 810, 616, 624, 253 |
| 2 | 405, 308, 312, 253 |
| 2 | 405, 154, 156, 253 |
| 3 | 405, 77, 78, 253 |
| 11 | 135, 77, 26, 253 |
| 135, 7, 26, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 135 x 7 x 26 x 23 = 149189040
Therefore, the lowest common multiple of 810,616,624,253 is 149189040.
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.
810 x 616 x 624 x 253 = 78771813120
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
253 : 1, 11, 23, 253
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,616,624,253, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
616:2x 2x 2x 7x 11
624:2x 2x 2x 2x 3x 13
253:11x 23
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 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 78771813120/(1x528)
LCM = 78771813120/528
LCM = 149189040
Thus, we can understand that the LCM of 810,616,624,253 is 149189040.
