Given numbers are 604,176,748,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 604,176,748,690 is 155868240.
Find LCM of 604,176,748,690 with Prime Factorization
| 2 | 604, 176, 748, 690 |
| 2 | 302, 88, 374, 345 |
| 11 | 151, 44, 187, 345 |
| 151, 4, 17, 345 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 151 x 4 x 17 x 345 = 155868240
Therefore, the lowest common multiple of 604,176,748,690 is 155868240.
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.
604 x 176 x 748 x 690 = 54865620480
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.
604 : 1, 2, 4, 151, 302, 604
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 604,176,748,690, is 2.
Now, the common factors can be found like this.
604:2x 2x 151
176:2x 2x 2x 2x 11
748:2x 2x 11x 17
690:2x 3x 5x 23
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 54865620480/(2x176)
LCM = 54865620480/352
LCM = 155868240
Thus, we can understand that the LCM of 604,176,748,690 is 155868240.
