Given numbers are 101,728,851,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 101,728,851,391 is 1063729576.
Find LCM of 101,728,851,391 with Prime Factorization
| 23 | 101, 728, 851, 391 |
| 101, 728, 37, 17 |
Multiply the prime numbers at the bottom and the left side.
23 x 101 x 728 x 37 x 17 = 1063729576
Therefore, the lowest common multiple of 101,728,851,391 is 1063729576.
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.
101 x 728 x 851 x 391 = 24465780248
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.
101 : 1, 101
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
851 : 1, 23, 37, 851
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,728,851,391, is 1.
Now, the common factors can be found like this.
101:101
728:2x 2x 2x 7x 13
851:23x 37
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 24465780248/(1x23)
LCM = 24465780248/23
LCM = 1063729576
Thus, we can understand that the LCM of 101,728,851,391 is 1063729576.
