Given numbers are 991,942,767,971,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,942,767,971,715 is 38238587428470.
Find LCM of 991,942,767,971,715 with Prime Factorization
13 | 991, 942, 767, 971, 715 |
991, 942, 59, 971, 55 |
Multiply the prime numbers at the bottom and the left side.
13 x 991 x 942 x 59 x 971 x 55 = 38238587428470
Therefore, the lowest common multiple of 991,942,767,971,715 is 38238587428470.
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.
991 x 942 x 767 x 971 x 715 = 497101636570110
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.
991 : 1, 991
942 : 1, 2, 3, 6, 157, 314, 471, 942
767 : 1, 13, 59, 767
971 : 1, 971
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,942,767,971,715, is 1.
Now, the common factors can be found like this.
991:991
942:2x 3x 157
767:13x 59
971:971
715:5x 11x 13
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 = 497101636570110/(1x13)
LCM = 497101636570110/13
LCM = 38238587428470
Thus, we can understand that the LCM of 991,942,767,971,715 is 38238587428470.
