Given numbers are 910,278,788,399,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 910,278,788,399,724 is 514168948020.
Find LCM of 910,278,788,399,724 with Prime Factorization
| 2 | 910, 278, 788, 399, 724 |
| 2 | 455, 139, 394, 399, 362 |
| 7 | 455, 139, 197, 399, 181 |
| 65, 139, 197, 57, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 65 x 139 x 197 x 57 x 181 = 514168948020
Therefore, the lowest common multiple of 910,278,788,399,724 is 514168948020.
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.
910 x 278 x 788 x 399 x 724 = 57586922178240
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
278 : 1, 2, 139, 278
788 : 1, 2, 4, 197, 394, 788
399 : 1, 3, 7, 19, 21, 57, 133, 399
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,278,788,399,724, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
278:2x 139
788:2x 2x 197
399:3x 7x 19
724:2x 2x 181
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 7 = 112
Therefore, the value for common factors is 112.
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 = 57586922178240/(1x112)
LCM = 57586922178240/112
LCM = 514168948020
Thus, we can understand that the LCM of 910,278,788,399,724 is 514168948020.
