Given numbers are 921,209,390,901,893
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,209,390,901,893 is 1059673118790.
Find LCM of 921,209,390,901,893 with Prime Factorization
3 | 921, 209, 390, 901, 893 |
19 | 307, 209, 130, 901, 893 |
307, 11, 130, 901, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 307 x 11 x 130 x 901 x 47 = 1059673118790
Therefore, the lowest common multiple of 921,209,390,901,893 is 1059673118790.
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 209 x 390 x 901 x 893 = 60401367771030
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
209 : 1, 11, 19, 209
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
901 : 1, 17, 53, 901
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,209,390,901,893, is 1.
Now, the common factors can be found like this.
921:3x 307
209:11x 19
390:2x 3x 5x 13
901:17x 53
893:19x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 60401367771030/(1x57)
LCM = 60401367771030/57
LCM = 1059673118790
Thus, we can understand that the LCM of 921,209,390,901,893 is 1059673118790.
