Given numbers are 820,360,916,472
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,360,916,472 is 199422360.
Find LCM of 820,360,916,472 with Prime Factorization
2 | 820, 360, 916, 472 |
2 | 410, 180, 458, 236 |
2 | 205, 90, 229, 118 |
5 | 205, 45, 229, 59 |
41, 9, 229, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 41 x 9 x 229 x 59 = 199422360
Therefore, the lowest common multiple of 820,360,916,472 is 199422360.
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.
820 x 360 x 916 x 472 = 127630310400
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
916 : 1, 2, 4, 229, 458, 916
472 : 1, 2, 4, 8, 59, 118, 236, 472
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,360,916,472, is 4.
Now, the common factors can be found like this.
820:2x 2x 5x 41
360:2x 2x 2x 3x 3x 5
916:2x 2x 229
472:2x 2x 2x 59
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 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 127630310400/(4x160)
LCM = 127630310400/640
LCM = 199422360
Thus, we can understand that the LCM of 820,360,916,472 is 199422360.
