Given numbers are 752,918,312,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 752,918,312,947 is 4249363248.
Find LCM of 752,918,312,947 with Prime Factorization
| 2 | 752, 918, 312, 947 |
| 2 | 376, 459, 156, 947 |
| 2 | 188, 459, 78, 947 |
| 3 | 94, 459, 39, 947 |
| 94, 153, 13, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 94 x 153 x 13 x 947 = 4249363248
Therefore, the lowest common multiple of 752,918,312,947 is 4249363248.
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.
752 x 918 x 312 x 947 = 203969435904
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.
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 752,918,312,947, is 1.
Now, the common factors can be found like this.
752:2x 2x 2x 2x 47
918:2x 3x 3x 3x 17
312:2x 2x 2x 3x 13
947:947
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 3 = 48
Therefore, the value for common factors is 48.
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 = 203969435904/(1x48)
LCM = 203969435904/48
LCM = 4249363248
Thus, we can understand that the LCM of 752,918,312,947 is 4249363248.
