Given numbers are 974,120,692,644,160
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,120,692,644,160 is 6510917280.
Find LCM of 974,120,692,644,160 with Prime Factorization
| 2 | 974, 120, 692, 644, 160 |
| 2 | 487, 60, 346, 322, 80 |
| 2 | 487, 30, 173, 161, 40 |
| 5 | 487, 15, 173, 161, 20 |
| 487, 3, 173, 161, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 487 x 3 x 173 x 161 x 4 = 6510917280
Therefore, the lowest common multiple of 974,120,692,644,160 is 6510917280.
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.
974 x 120 x 692 x 644 x 160 = 8333974118400
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.
974 : 1, 2, 487, 974
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
692 : 1, 2, 4, 173, 346, 692
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,120,692,644,160, is 2.
Now, the common factors can be found like this.
974:2x 487
120:2x 2x 2x 3x 5
692:2x 2x 173
644:2x 2x 7x 23
160:2x 2x 2x 2x 2x 5
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 2x 2x 5 = 640
Therefore, the value for common factors is 640.
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 = 8333974118400/(2x640)
LCM = 8333974118400/1280
LCM = 6510917280
Thus, we can understand that the LCM of 974,120,692,644,160 is 6510917280.
