Given numbers are 921,905,453,977,151
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,905,453,977,151 is 122964492135.
Find LCM of 921,905,453,977,151 with Prime Factorization
3 | 921, 905, 453, 977, 151 |
151 | 307, 905, 151, 977, 151 |
307, 905, 1, 977, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 151 x 307 x 905 x 1 x 977 x 1 = 122964492135
Therefore, the lowest common multiple of 921,905,453,977,151 is 122964492135.
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.
921 x 905 x 453 x 977 x 151 = 55702914937155
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.
921 : 1, 3, 307, 921
905 : 1, 5, 181, 905
453 : 1, 3, 151, 453
977 : 1, 977
151 : 1, 151
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,905,453,977,151, is 1.
Now, the common factors can be found like this.
921:3x 307
905:5x 181
453:3x 151
977:977
151:151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 151 = 453
Therefore, the value for common factors is 453.
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 = 55702914937155/(1x453)
LCM = 55702914937155/453
LCM = 122964492135
Thus, we can understand that the LCM of 921,905,453,977,151 is 122964492135.
