Given numbers are 366,154,749,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 366,154,749,640 is 964951680.
Find LCM of 366,154,749,640 with Prime Factorization
| 2 | 366, 154, 749, 640 |
| 7 | 183, 77, 749, 320 |
| 183, 11, 107, 320 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 183 x 11 x 107 x 320 = 964951680
Therefore, the lowest common multiple of 366,154,749,640 is 964951680.
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.
366 x 154 x 749 x 640 = 27018647040
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.
366 : 1, 2, 3, 6, 61, 122, 183, 366
154 : 1, 2, 7, 11, 14, 22, 77, 154
749 : 1, 7, 107, 749
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 366,154,749,640, is 1.
Now, the common factors can be found like this.
366:2x 3x 61
154:2x 7x 11
749:7x 107
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 7 = 28
Therefore, the value for common factors is 28.
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 = 27018647040/(1x28)
LCM = 27018647040/28
LCM = 964951680
Thus, we can understand that the LCM of 366,154,749,640 is 964951680.
