Given numbers are 909,926,374,955,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,926,374,955,221 is 1954173863070.
Find LCM of 909,926,374,955,221 with Prime Factorization
| 2 | 909, 926, 374, 955, 221 |
| 17 | 909, 463, 187, 955, 221 |
| 909, 463, 11, 955, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 909 x 463 x 11 x 955 x 13 = 1954173863070
Therefore, the lowest common multiple of 909,926,374,955,221 is 1954173863070.
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.
909 x 926 x 374 x 955 x 221 = 66441911344380
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.
909 : 1, 3, 9, 101, 303, 909
926 : 1, 2, 463, 926
374 : 1, 2, 11, 17, 22, 34, 187, 374
955 : 1, 5, 191, 955
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,926,374,955,221, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
926:2x 463
374:2x 11x 17
955:5x 191
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 66441911344380/(1x34)
LCM = 66441911344380/34
LCM = 1954173863070
Thus, we can understand that the LCM of 909,926,374,955,221 is 1954173863070.
