Given numbers are 398,490,695,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,490,695,724 is 4906508180.
Find LCM of 398,490,695,724 with Prime Factorization
2 | 398, 490, 695, 724 |
5 | 199, 245, 695, 362 |
199, 49, 139, 362 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 199 x 49 x 139 x 362 = 4906508180
Therefore, the lowest common multiple of 398,490,695,724 is 4906508180.
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.
398 x 490 x 695 x 724 = 98130163600
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.
398 : 1, 2, 199, 398
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
695 : 1, 5, 139, 695
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,490,695,724, is 1.
Now, the common factors can be found like this.
398:2x 199
490:2x 5x 7x 7
695:5x 139
724:2x 2x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 98130163600/(1x20)
LCM = 98130163600/20
LCM = 4906508180
Thus, we can understand that the LCM of 398,490,695,724 is 4906508180.
