Given numbers are 749,687,260,155,511
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,687,260,155,511 is 302758577940.
Find LCM of 749,687,260,155,511 with Prime Factorization
5 | 749, 687, 260, 155, 511 |
7 | 749, 687, 52, 31, 511 |
107, 687, 52, 31, 73 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 107 x 687 x 52 x 31 x 73 = 302758577940
Therefore, the lowest common multiple of 749,687,260,155,511 is 302758577940.
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.
749 x 687 x 260 x 155 x 511 = 10596550227900
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.
749 : 1, 7, 107, 749
687 : 1, 3, 229, 687
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
155 : 1, 5, 31, 155
511 : 1, 7, 73, 511
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,687,260,155,511, is 1.
Now, the common factors can be found like this.
749:7x 107
687:3x 229
260:2x 2x 5x 13
155:5x 31
511:7x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 10596550227900/(1x35)
LCM = 10596550227900/35
LCM = 302758577940
Thus, we can understand that the LCM of 749,687,260,155,511 is 302758577940.
