Given numbers are 715,721,767,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,721,767,438 is 13321938630.
Find LCM of 715,721,767,438 with Prime Factorization
13 | 715, 721, 767, 438 |
55, 721, 59, 438 |
Multiply the prime numbers at the bottom and the left side.
13 x 55 x 721 x 59 x 438 = 13321938630
Therefore, the lowest common multiple of 715,721,767,438 is 13321938630.
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.
715 x 721 x 767 x 438 = 173185202190
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
721 : 1, 7, 103, 721
767 : 1, 13, 59, 767
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,721,767,438, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
721:7x 103
767:13x 59
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 173185202190/(1x13)
LCM = 173185202190/13
LCM = 13321938630
Thus, we can understand that the LCM of 715,721,767,438 is 13321938630.
