Given numbers are 684,847,210,624
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,847,210,624 is 150630480.
Find LCM of 684,847,210,624 with Prime Factorization
| 2 | 684, 847, 210, 624 |
| 2 | 342, 847, 105, 312 |
| 3 | 171, 847, 105, 156 |
| 7 | 57, 847, 35, 52 |
| 57, 121, 5, 52 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 57 x 121 x 5 x 52 = 150630480
Therefore, the lowest common multiple of 684,847,210,624 is 150630480.
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.
684 x 847 x 210 x 624 = 75917761920
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
847 : 1, 7, 11, 77, 121, 847
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,847,210,624, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
847:7x 11x 11
210:2x 3x 5x 7
624:2x 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 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 75917761920/(1x504)
LCM = 75917761920/504
LCM = 150630480
Thus, we can understand that the LCM of 684,847,210,624 is 150630480.
