Given numbers are 772,763,623,840,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,763,623,840,146 is 114809006760.
Find LCM of 772,763,623,840,146 with Prime Factorization
| 2 | 772, 763, 623, 840, 146 |
| 2 | 386, 763, 623, 420, 73 |
| 7 | 193, 763, 623, 210, 73 |
| 193, 109, 89, 30, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 193 x 109 x 89 x 30 x 73 = 114809006760
Therefore, the lowest common multiple of 772,763,623,840,146 is 114809006760.
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.
772 x 763 x 623 x 840 x 146 = 45005130649920
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.
772 : 1, 2, 4, 193, 386, 772
763 : 1, 7, 109, 763
623 : 1, 7, 89, 623
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
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,763,623,840,146, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
763:7x 109
623:7x 89
840:2x 2x 2x 3x 5x 7
146:2x 73
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 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 45005130649920/(1x392)
LCM = 45005130649920/392
LCM = 114809006760
Thus, we can understand that the LCM of 772,763,623,840,146 is 114809006760.
