Given numbers are 220,372,820,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,372,820,248 is 1677720.
Find LCM of 220,372,820,248 with Prime Factorization
| 2 | 220, 372, 820, 248 |
| 2 | 110, 186, 410, 124 |
| 5 | 55, 93, 205, 62 |
| 31 | 11, 93, 41, 62 |
| 11, 3, 41, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 11 x 3 x 41 x 2 = 1677720
Therefore, the lowest common multiple of 220,372,820,248 is 1677720.
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.
220 x 372 x 820 x 248 = 16642982400
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
248 : 1, 2, 4, 8, 31, 62, 124, 248
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,372,820,248, is 4.
Now, the common factors can be found like this.
220:2x 2x 5x 11
372:2x 2x 3x 31
820:2x 2x 5x 41
248:2x 2x 2x 31
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 2x 5x 31 = 2480
Therefore, the value for common factors is 2480.
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 = 16642982400/(4x2480)
LCM = 16642982400/9920
LCM = 1677720
Thus, we can understand that the LCM of 220,372,820,248 is 1677720.
