Find LCM of 892,420,399,407,222 with Prime Factorization
| 2 | 892, 420, 399, 407, 222 |
| 2 | 446, 210, 399, 407, 111 |
| 3 | 223, 105, 399, 407, 111 |
| 7 | 223, 35, 133, 407, 37 |
| 37 | 223, 5, 19, 407, 37 |
| 223, 5, 19, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 37 x 223 x 5 x 19 x 11 x 1 = 724272780
Therefore, the lowest common multiple of 892,420,399,407,222 is 724272780.
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.
892 x 420 x 399 x 407 x 222 = 13506238801440
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.
892 : 1, 2, 4, 223, 446, 892
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
399 : 1, 3, 7, 19, 21, 57, 133, 399
407 : 1, 11, 37, 407
222 : 1, 2, 3, 6, 37, 74, 111, 222
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,420,399,407,222, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
420:2x 2x 3x 5x 7
399:3x 7x 19
407:11x 37
222:2x 3x 37
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 3x 3x 7x 37 = 18648
Therefore, the value for common factors is 18648.
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 = 13506238801440/(1x18648)
LCM = 13506238801440/18648
LCM = 724272780
Thus, we can understand that the LCM of 892,420,399,407,222 is 724272780.
