Given numbers are 761,985,490,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 761,985,490,707 is 7419392330.
Find LCM of 761,985,490,707 with Prime Factorization
| 5 | 761, 985, 490, 707 |
| 7 | 761, 197, 98, 707 |
| 761, 197, 14, 101 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 761 x 197 x 14 x 101 = 7419392330
Therefore, the lowest common multiple of 761,985,490,707 is 7419392330.
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.
761 x 985 x 490 x 707 = 259678731550
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.
761 : 1, 761
985 : 1, 5, 197, 985
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 761,985,490,707, is 1.
Now, the common factors can be found like this.
761:761
985:5x 197
490:2x 5x 7x 7
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.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 259678731550/(1x35)
LCM = 259678731550/35
LCM = 7419392330
Thus, we can understand that the LCM of 761,985,490,707 is 7419392330.
