Given numbers are 801,220,242,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 801,220,242,140 is 13568940.
Find LCM of 801,220,242,140 with Prime Factorization
| 2 | 801, 220, 242, 140 |
| 2 | 801, 110, 121, 70 |
| 5 | 801, 55, 121, 35 |
| 11 | 801, 11, 121, 7 |
| 801, 1, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 801 x 1 x 11 x 7 = 13568940
Therefore, the lowest common multiple of 801,220,242,140 is 13568940.
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.
801 x 220 x 242 x 140 = 5970333600
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.
801 : 1, 3, 9, 89, 267, 801
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
242 : 1, 2, 11, 22, 121, 242
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,220,242,140, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
220:2x 2x 5x 11
242:2x 11x 11
140:2x 2x 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.
2x 2x 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 5970333600/(1x440)
LCM = 5970333600/440
LCM = 13568940
Thus, we can understand that the LCM of 801,220,242,140 is 13568940.
