Given numbers are 758,379,620,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 758,379,620,398 is 46761020.
Find LCM of 758,379,620,398 with Prime Factorization
2 | 758, 379, 620, 398 |
379 | 379, 379, 310, 199 |
1, 1, 310, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 379 x 1 x 1 x 310 x 199 = 46761020
Therefore, the lowest common multiple of 758,379,620,398 is 46761020.
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.
758 x 379 x 620 x 398 = 70889706320
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.
758 : 1, 2, 379, 758
379 : 1, 379
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,379,620,398, is 1.
Now, the common factors can be found like this.
758:2x 379
379:379
620:2x 2x 5x 31
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 379 = 1516
Therefore, the value for common factors is 1516.
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 = 70889706320/(1x1516)
LCM = 70889706320/1516
LCM = 46761020
Thus, we can understand that the LCM of 758,379,620,398 is 46761020.
