Given numbers are 403,637,202,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,637,202,175 is 99722350.
Find LCM of 403,637,202,175 with Prime Factorization
| 7 | 403, 637, 202, 175 |
| 13 | 403, 91, 202, 25 |
| 31, 7, 202, 25 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 31 x 7 x 202 x 25 = 99722350
Therefore, the lowest common multiple of 403,637,202,175 is 99722350.
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.
403 x 637 x 202 x 175 = 9074733850
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.
403 : 1, 13, 31, 403
637 : 1, 7, 13, 49, 91, 637
202 : 1, 2, 101, 202
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,637,202,175, is 1.
Now, the common factors can be found like this.
403:13x 31
637:7x 7x 13
202:2x 101
175:5x 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.
7x 13 = 91
Therefore, the value for common factors is 91.
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 = 9074733850/(1x91)
LCM = 9074733850/91
LCM = 99722350
Thus, we can understand that the LCM of 403,637,202,175 is 99722350.
