Given numbers are 564,851,690,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 564,851,690,777 is 16798740.
Find LCM of 564,851,690,777 with Prime Factorization
| 2 | 564, 851, 690, 777 |
| 3 | 282, 851, 345, 777 |
| 23 | 94, 851, 115, 259 |
| 37 | 94, 37, 5, 259 |
| 94, 1, 5, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 37 x 94 x 1 x 5 x 7 = 16798740
Therefore, the lowest common multiple of 564,851,690,777 is 16798740.
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.
564 x 851 x 690 x 777 = 257323099320
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.
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
851 : 1, 23, 37, 851
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,851,690,777, is 1.
Now, the common factors can be found like this.
564:2x 2x 3x 47
851:23x 37
690:2x 3x 5x 23
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 23x 37 = 15318
Therefore, the value for common factors is 15318.
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 = 257323099320/(1x15318)
LCM = 257323099320/15318
LCM = 16798740
Thus, we can understand that the LCM of 564,851,690,777 is 16798740.
