Given numbers are 436,952,575,781,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 436,952,575,781,721 is 4799760303800.
Find LCM of 436,952,575,781,721 with Prime Factorization
| 2 | 436, 952, 575, 781, 721 |
| 2 | 218, 476, 575, 781, 721 |
| 7 | 109, 238, 575, 781, 721 |
| 109, 34, 575, 781, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 109 x 34 x 575 x 781 x 103 = 4799760303800
Therefore, the lowest common multiple of 436,952,575,781,721 is 4799760303800.
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.
436 x 952 x 575 x 781 x 721 = 134393288506400
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.
436 : 1, 2, 4, 109, 218, 436
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
575 : 1, 5, 23, 25, 115, 575
781 : 1, 11, 71, 781
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,952,575,781,721, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
952:2x 2x 2x 7x 17
575:5x 5x 23
781:11x 71
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 134393288506400/(1x28)
LCM = 134393288506400/28
LCM = 4799760303800
Thus, we can understand that the LCM of 436,952,575,781,721 is 4799760303800.
