Given numbers are 730,700,840,977
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,700,840,977 is 299548200.
Find LCM of 730,700,840,977 with Prime Factorization
| 2 | 730, 700, 840, 977 |
| 2 | 365, 350, 420, 977 |
| 5 | 365, 175, 210, 977 |
| 7 | 73, 35, 42, 977 |
| 73, 5, 6, 977 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 73 x 5 x 6 x 977 = 299548200
Therefore, the lowest common multiple of 730,700,840,977 is 299548200.
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.
730 x 700 x 840 x 977 = 419367480000
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
977 : 1, 977
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,700,840,977, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
700:2x 2x 5x 5x 7
840:2x 2x 2x 3x 5x 7
977:977
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 5x 5x 7 = 1400
Therefore, the value for common factors is 1400.
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 = 419367480000/(1x1400)
LCM = 419367480000/1400
LCM = 299548200
Thus, we can understand that the LCM of 730,700,840,977 is 299548200.
