Given numbers are 723,493,533,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,493,533,221 is 189981987.
Find LCM of 723,493,533,221 with Prime Factorization
| 13 | 723, 493, 533, 221 |
| 17 | 723, 493, 41, 17 |
| 723, 29, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 723 x 29 x 41 x 1 = 189981987
Therefore, the lowest common multiple of 723,493,533,221 is 189981987.
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.
723 x 493 x 533 x 221 = 41986019127
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.
723 : 1, 3, 241, 723
493 : 1, 17, 29, 493
533 : 1, 13, 41, 533
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,493,533,221, is 1.
Now, the common factors can be found like this.
723:3x 241
493:17x 29
533:13x 41
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.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 41986019127/(1x221)
LCM = 41986019127/221
LCM = 189981987
Thus, we can understand that the LCM of 723,493,533,221 is 189981987.
