Given numbers are 679,355,150,136,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 679,355,150,136,390 is 6392513400.
Find LCM of 679,355,150,136,390 with Prime Factorization
| 2 | 679, 355, 150, 136, 390 |
| 3 | 679, 355, 75, 68, 195 |
| 5 | 679, 355, 25, 68, 65 |
| 679, 71, 5, 68, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 679 x 71 x 5 x 68 x 13 = 6392513400
Therefore, the lowest common multiple of 679,355,150,136,390 is 6392513400.
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.
679 x 355 x 150 x 136 x 390 = 1917754020000
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.
679 : 1, 7, 97, 679
355 : 1, 5, 71, 355
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
136 : 1, 2, 4, 8, 17, 34, 68, 136
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,355,150,136,390, is 1.
Now, the common factors can be found like this.
679:7x 97
355:5x 71
150:2x 3x 5x 5
136:2x 2x 2x 17
390:2x 3x 5x 13
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 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 1917754020000/(1x300)
LCM = 1917754020000/300
LCM = 6392513400
Thus, we can understand that the LCM of 679,355,150,136,390 is 6392513400.
