Given numbers are 735,921,986,781,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 735,921,986,781,707 is 17549915799570.
Find LCM of 735,921,986,781,707 with Prime Factorization
| 3 | 735, 921, 986, 781, 707 |
| 7 | 245, 307, 986, 781, 707 |
| 35, 307, 986, 781, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 35 x 307 x 986 x 781 x 101 = 17549915799570
Therefore, the lowest common multiple of 735,921,986,781,707 is 17549915799570.
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.
735 x 921 x 986 x 781 x 707 = 368548231790970
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.
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
921 : 1, 3, 307, 921
986 : 1, 2, 17, 29, 34, 58, 493, 986
781 : 1, 11, 71, 781
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,921,986,781,707, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
921:3x 307
986:2x 17x 29
781:11x 71
707:7x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 368548231790970/(1x21)
LCM = 368548231790970/21
LCM = 17549915799570
Thus, we can understand that the LCM of 735,921,986,781,707 is 17549915799570.
