Given numbers are 763,761,406,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 763,761,406,661 is 22260691334.
Find LCM of 763,761,406,661 with Prime Factorization
| 7 | 763, 761, 406, 661 |
| 109, 761, 58, 661 |
Multiply the prime numbers at the bottom and the left side.
7 x 109 x 761 x 58 x 661 = 22260691334
Therefore, the lowest common multiple of 763,761,406,661 is 22260691334.
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.
763 x 761 x 406 x 661 = 155824839338
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.
763 : 1, 7, 109, 763
761 : 1, 761
406 : 1, 2, 7, 14, 29, 58, 203, 406
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,761,406,661, is 1.
Now, the common factors can be found like this.
763:7x 109
761:761
406:2x 7x 29
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 155824839338/(1x7)
LCM = 155824839338/7
LCM = 22260691334
Thus, we can understand that the LCM of 763,761,406,661 is 22260691334.
