Given numbers are 721,901,671,610
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,901,671,610 is 4358956910.
Find LCM of 721,901,671,610 with Prime Factorization
61 | 721, 901, 671, 610 |
721, 901, 11, 10 |
Multiply the prime numbers at the bottom and the left side.
61 x 721 x 901 x 11 x 10 = 4358956910
Therefore, the lowest common multiple of 721,901,671,610 is 4358956910.
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.
721 x 901 x 671 x 610 = 265896371510
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.
721 : 1, 7, 103, 721
901 : 1, 17, 53, 901
671 : 1, 11, 61, 671
610 : 1, 2, 5, 10, 61, 122, 305, 610
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,901,671,610, is 1.
Now, the common factors can be found like this.
721:7x 103
901:17x 53
671:11x 61
610:2x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
61 = 61
Therefore, the value for common factors is 61.
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 = 265896371510/(1x61)
LCM = 265896371510/61
LCM = 4358956910
Thus, we can understand that the LCM of 721,901,671,610 is 4358956910.
