Given numbers are 364,689,781,265
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 364,689,781,265 is 75335260.
Find LCM of 364,689,781,265 with Prime Factorization
| 13 | 364, 689, 781, 265 |
| 53 | 28, 53, 781, 265 |
| 28, 1, 781, 5 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 28 x 1 x 781 x 5 = 75335260
Therefore, the lowest common multiple of 364,689,781,265 is 75335260.
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.
364 x 689 x 781 x 265 = 51905994140
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
689 : 1, 13, 53, 689
781 : 1, 11, 71, 781
265 : 1, 5, 53, 265
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,689,781,265, is 1.
Now, the common factors can be found like this.
364:2x 2x 7x 13
689:13x 53
781:11x 71
265:5x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 53 = 689
Therefore, the value for common factors is 689.
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 = 51905994140/(1x689)
LCM = 51905994140/689
LCM = 75335260
Thus, we can understand that the LCM of 364,689,781,265 is 75335260.
