Given numbers are 421,695,409,417,372
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,695,409,417,372 is 44517744060.
Find LCM of 421,695,409,417,372 with Prime Factorization
| 3 | 421, 695, 409, 417, 372 |
| 139 | 421, 695, 409, 139, 124 |
| 421, 5, 409, 1, 124 |
Multiply the prime numbers at the bottom and the left side.
3 x 139 x 421 x 5 x 409 x 1 x 124 = 44517744060
Therefore, the lowest common multiple of 421,695,409,417,372 is 44517744060.
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.
421 x 695 x 409 x 417 x 372 = 18563899273020
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.
421 : 1, 421
695 : 1, 5, 139, 695
409 : 1, 409
417 : 1, 3, 139, 417
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,695,409,417,372, is 1.
Now, the common factors can be found like this.
421:421
695:5x 139
409:409
417:3x 139
372:2x 2x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 139 = 417
Therefore, the value for common factors is 417.
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 = 18563899273020/(1x417)
LCM = 18563899273020/417
LCM = 44517744060
Thus, we can understand that the LCM of 421,695,409,417,372 is 44517744060.
