Given numbers are 697,490,861,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,490,861,670 is 68647530.
Find LCM of 697,490,861,670 with Prime Factorization
2 | 697, 490, 861, 670 |
5 | 697, 245, 861, 335 |
7 | 697, 49, 861, 67 |
41 | 697, 7, 123, 67 |
17, 7, 3, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 41 x 17 x 7 x 3 x 67 = 68647530
Therefore, the lowest common multiple of 697,490,861,670 is 68647530.
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.
697 x 490 x 861 x 670 = 197018411100
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.
697 : 1, 17, 41, 697
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
861 : 1, 3, 7, 21, 41, 123, 287, 861
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,490,861,670, is 1.
Now, the common factors can be found like this.
697:17x 41
490:2x 5x 7x 7
861:3x 7x 41
670:2x 5x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 41 = 2870
Therefore, the value for common factors is 2870.
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 = 197018411100/(1x2870)
LCM = 197018411100/2870
LCM = 68647530
Thus, we can understand that the LCM of 697,490,861,670 is 68647530.
