Given numbers are 910,913,694,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 910,913,694,640 is 18451072640.
Find LCM of 910,913,694,640 with Prime Factorization
| 2 | 910, 913, 694, 640 |
| 5 | 455, 913, 347, 320 |
| 91, 913, 347, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 91 x 913 x 347 x 64 = 18451072640
Therefore, the lowest common multiple of 910,913,694,640 is 18451072640.
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 913 x 694 x 640 = 369021452800
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
913 : 1, 11, 83, 913
694 : 1, 2, 347, 694
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,913,694,640, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
913:11x 83
694:2x 347
640:2x 2x 2x 2x 2x 2x 2x 5
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 5 = 20
Therefore, the value for common factors is 20.
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 = 369021452800/(1x20)
LCM = 369021452800/20
LCM = 18451072640
Thus, we can understand that the LCM of 910,913,694,640 is 18451072640.
