Given numbers are 639,121,899,290
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,121,899,290 is 695097810.
Find LCM of 639,121,899,290 with Prime Factorization
29 | 639, 121, 899, 290 |
639, 121, 31, 10 |
Multiply the prime numbers at the bottom and the left side.
29 x 639 x 121 x 31 x 10 = 695097810
Therefore, the lowest common multiple of 639,121,899,290 is 695097810.
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.
639 x 121 x 899 x 290 = 20157836490
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.
639 : 1, 3, 9, 71, 213, 639
121 : 1, 11, 121
899 : 1, 29, 31, 899
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,121,899,290, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
121:11x 11
899:29x 31
290:2x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29 = 29
Therefore, the value for common factors is 29.
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 = 20157836490/(1x29)
LCM = 20157836490/29
LCM = 695097810
Thus, we can understand that the LCM of 639,121,899,290 is 695097810.
