Given numbers are 721,909,606,202,885
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,909,606,202,885 is 386679510.
Find LCM of 721,909,606,202,885 with Prime Factorization
| 2 | 721, 909, 606, 202, 885 |
| 3 | 721, 909, 303, 101, 885 |
| 101 | 721, 101, 303, 101, 295 |
| 721, 1, 3, 1, 295 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 101 x 721 x 1 x 3 x 1 x 295 = 386679510
Therefore, the lowest common multiple of 721,909,606,202,885 is 386679510.
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 909 x 606 x 202 x 885 = 71001318267180
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
909 : 1, 3, 9, 101, 303, 909
606 : 1, 2, 3, 6, 101, 202, 303, 606
202 : 1, 2, 101, 202
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,909,606,202,885, is 1.
Now, the common factors can be found like this.
721:7x 103
909:3x 3x 101
606:2x 3x 101
202:2x 101
885:3x 5x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 101x 101 = 183618
Therefore, the value for common factors is 183618.
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 = 71001318267180/(1x183618)
LCM = 71001318267180/183618
LCM = 386679510
Thus, we can understand that the LCM of 721,909,606,202,885 is 386679510.
