Given numbers are 971,804,320,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 971,804,320,312 is 811911360.
Find LCM of 971,804,320,312 with Prime Factorization
2 | 971, 804, 320, 312 |
2 | 971, 402, 160, 156 |
2 | 971, 201, 80, 78 |
3 | 971, 201, 40, 39 |
971, 67, 40, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 971 x 67 x 40 x 13 = 811911360
Therefore, the lowest common multiple of 971,804,320,312 is 811911360.
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.
971 x 804 x 320 x 312 = 77943490560
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.
971 : 1, 971
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,804,320,312, is 1.
Now, the common factors can be found like this.
971:971
804:2x 2x 3x 67
320:2x 2x 2x 2x 2x 2x 5
312:2x 2x 2x 3x 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 2x 2x 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 77943490560/(1x96)
LCM = 77943490560/96
LCM = 811911360
Thus, we can understand that the LCM of 971,804,320,312 is 811911360.
