Given numbers are 472,698,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 472,698,221 is 36404888.
Find LCM of 472,698,221 with Prime Factorization
| 2 | 472, 698, 221 |
| 236, 349, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 236 x 349 x 221 = 36404888
Therefore, the lowest common multiple of 472,698,221 is 36404888.
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.
472 x 698 x 221 = 72809776
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.
472 : 1, 2, 4, 8, 59, 118, 236, 472
698 : 1, 2, 349, 698
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,698,221, is 1.
Now, the common factors can be found like this.
472:2x 2x 2x 59
698:2x 349
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.
2 = 2
Therefore, the value for common factors is 2.
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 = 72809776/(1x2)
LCM = 72809776/2
LCM = 36404888
Thus, we can understand that the LCM of 472,698,221 is 36404888.
