Given numbers are 398,452,390,220,875
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,452,390,220,875 is 33764230500.
Find LCM of 398,452,390,220,875 with Prime Factorization
2 | 398, 452, 390, 220, 875 |
2 | 199, 226, 195, 110, 875 |
5 | 199, 113, 195, 55, 875 |
199, 113, 39, 11, 175 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 199 x 113 x 39 x 11 x 175 = 33764230500
Therefore, the lowest common multiple of 398,452,390,220,875 is 33764230500.
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 452 x 390 x 220 x 875 = 13505692200000
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
452 : 1, 2, 4, 113, 226, 452
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
875 : 1, 5, 7, 25, 35, 125, 175, 875
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,452,390,220,875, is 1.
Now, the common factors can be found like this.
398:2x 199
452:2x 2x 113
390:2x 3x 5x 13
220:2x 2x 5x 11
875:5x 5x 5x 7
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 2x 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 13505692200000/(1x400)
LCM = 13505692200000/400
LCM = 33764230500
Thus, we can understand that the LCM of 398,452,390,220,875 is 33764230500.
