Given numbers are 278,787,715,871,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,787,715,871,651 is 6823094107830.
Find LCM of 278,787,715,871,651 with Prime Factorization
13 | 278, 787, 715, 871, 651 |
278, 787, 55, 67, 651 |
Multiply the prime numbers at the bottom and the left side.
13 x 278 x 787 x 55 x 67 x 651 = 6823094107830
Therefore, the lowest common multiple of 278,787,715,871,651 is 6823094107830.
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.
278 x 787 x 715 x 871 x 651 = 88700223401790
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.
278 : 1, 2, 139, 278
787 : 1, 787
715 : 1, 5, 11, 13, 55, 65, 143, 715
871 : 1, 13, 67, 871
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,787,715,871,651, is 1.
Now, the common factors can be found like this.
278:2x 139
787:787
715:5x 11x 13
871:13x 67
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 88700223401790/(1x13)
LCM = 88700223401790/13
LCM = 6823094107830
Thus, we can understand that the LCM of 278,787,715,871,651 is 6823094107830.
