Given numbers are 770,221,357,737
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,221,357,737 is 34204170.
Find LCM of 770,221,357,737 with Prime Factorization
| 7 | 770, 221, 357, 737 |
| 11 | 110, 221, 51, 737 |
| 17 | 10, 221, 51, 67 |
| 10, 13, 3, 67 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 17 x 10 x 13 x 3 x 67 = 34204170
Therefore, the lowest common multiple of 770,221,357,737 is 34204170.
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.
770 x 221 x 357 x 737 = 44773258530
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
221 : 1, 13, 17, 221
357 : 1, 3, 7, 17, 21, 51, 119, 357
737 : 1, 11, 67, 737
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,221,357,737, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
221:13x 17
357:3x 7x 17
737:11x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 17 = 1309
Therefore, the value for common factors is 1309.
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 = 44773258530/(1x1309)
LCM = 44773258530/1309
LCM = 34204170
Thus, we can understand that the LCM of 770,221,357,737 is 34204170.
