Given numbers are 936,420,778,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 936,420,778,575 is 1465518600.
Find LCM of 936,420,778,575 with Prime Factorization
| 2 | 936, 420, 778, 575 |
| 2 | 468, 210, 389, 575 |
| 3 | 234, 105, 389, 575 |
| 5 | 78, 35, 389, 575 |
| 78, 7, 389, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 78 x 7 x 389 x 115 = 1465518600
Therefore, the lowest common multiple of 936,420,778,575 is 1465518600.
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.
936 x 420 x 778 x 575 = 175862232000
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.
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
778 : 1, 2, 389, 778
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,420,778,575, is 1.
Now, the common factors can be found like this.
936:2x 2x 2x 3x 3x 13
420:2x 2x 3x 5x 7
778:2x 389
575:5x 5x 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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 175862232000/(1x120)
LCM = 175862232000/120
LCM = 1465518600
Thus, we can understand that the LCM of 936,420,778,575 is 1465518600.
