Given numbers are 785,784,677,804,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,784,677,804,628 is 83747228880.
Find LCM of 785,784,677,804,628 with Prime Factorization
| 2 | 785, 784, 677, 804, 628 |
| 2 | 785, 392, 677, 402, 314 |
| 157 | 785, 196, 677, 201, 157 |
| 5, 196, 677, 201, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 157 x 5 x 196 x 677 x 201 x 1 = 83747228880
Therefore, the lowest common multiple of 785,784,677,804,628 is 83747228880.
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.
785 x 784 x 677 x 804 x 628 = 210373038946560
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.
785 : 1, 5, 157, 785
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
677 : 1, 677
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,784,677,804,628, is 1.
Now, the common factors can be found like this.
785:5x 157
784:2x 2x 2x 2x 7x 7
677:677
804:2x 2x 3x 67
628:2x 2x 157
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 157 = 2512
Therefore, the value for common factors is 2512.
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 = 210373038946560/(1x2512)
LCM = 210373038946560/2512
LCM = 83747228880
Thus, we can understand that the LCM of 785,784,677,804,628 is 83747228880.
