Given numbers are 697,221,921,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,221,921,910 is 584162670.
Find LCM of 697,221,921,910 with Prime Factorization
13 | 697, 221, 921, 910 |
17 | 697, 17, 921, 70 |
41, 1, 921, 70 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 41 x 1 x 921 x 70 = 584162670
Therefore, the lowest common multiple of 697,221,921,910 is 584162670.
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 221 x 921 x 910 = 129099950070
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
221 : 1, 13, 17, 221
921 : 1, 3, 307, 921
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,221,921,910, is 1.
Now, the common factors can be found like this.
697:17x 41
221:13x 17
921:3x 307
910:2x 5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 129099950070/(1x221)
LCM = 129099950070/221
LCM = 584162670
Thus, we can understand that the LCM of 697,221,921,910 is 584162670.
