Given numbers are 749,620,775,893
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,620,775,893 is 2073456700.
Find LCM of 749,620,775,893 with Prime Factorization
| 5 | 749, 620, 775, 893 |
| 31 | 749, 124, 155, 893 |
| 749, 4, 5, 893 |
Multiply the prime numbers at the bottom and the left side.
5 x 31 x 749 x 4 x 5 x 893 = 2073456700
Therefore, the lowest common multiple of 749,620,775,893 is 2073456700.
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.
749 x 620 x 775 x 893 = 321385788500
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.
749 : 1, 7, 107, 749
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
775 : 1, 5, 25, 31, 155, 775
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,620,775,893, is 1.
Now, the common factors can be found like this.
749:7x 107
620:2x 2x 5x 31
775:5x 5x 31
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.
5x 31 = 155
Therefore, the value for common factors is 155.
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 = 321385788500/(1x155)
LCM = 321385788500/155
LCM = 2073456700
Thus, we can understand that the LCM of 749,620,775,893 is 2073456700.
