Given numbers are 642,461,210,783,633
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,461,210,783,633 is 570462315570.
Find LCM of 642,461,210,783,633 with Prime Factorization
2 | 642, 461, 210, 783, 633 |
3 | 321, 461, 105, 783, 633 |
107, 461, 35, 261, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 461 x 35 x 261 x 211 = 570462315570
Therefore, the lowest common multiple of 642,461,210,783,633 is 570462315570.
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.
642 x 461 x 210 x 783 x 633 = 30804965040780
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
461 : 1, 461
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
783 : 1, 3, 9, 27, 29, 87, 261, 783
633 : 1, 3, 211, 633
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,461,210,783,633, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
461:461
210:2x 3x 5x 7
783:3x 3x 3x 29
633:3x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 30804965040780/(1x54)
LCM = 30804965040780/54
LCM = 570462315570
Thus, we can understand that the LCM of 642,461,210,783,633 is 570462315570.
