Given numbers are 672,365,420,569
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,365,420,569 is 139564320.
Find LCM of 672,365,420,569 with Prime Factorization
| 2 | 672, 365, 420, 569 |
| 2 | 336, 365, 210, 569 |
| 3 | 168, 365, 105, 569 |
| 5 | 56, 365, 35, 569 |
| 7 | 56, 73, 7, 569 |
| 8, 73, 1, 569 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 8 x 73 x 1 x 569 = 139564320
Therefore, the lowest common multiple of 672,365,420,569 is 139564320.
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.
672 x 365 x 420 x 569 = 58617014400
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
365 : 1, 5, 73, 365
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
569 : 1, 569
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,365,420,569, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
365:5x 73
420:2x 2x 3x 5x 7
569:569
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 7 = 420
Therefore, the value for common factors is 420.
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 = 58617014400/(1x420)
LCM = 58617014400/420
LCM = 139564320
Thus, we can understand that the LCM of 672,365,420,569 is 139564320.
