Given numbers are 121,697,421,628,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 121,697,421,628,869 is 1761517569724.
Find LCM of 121,697,421,628,869 with Prime Factorization
11 | 121, 697, 421, 628, 869 |
11, 697, 421, 628, 79 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 697 x 421 x 628 x 79 = 1761517569724
Therefore, the lowest common multiple of 121,697,421,628,869 is 1761517569724.
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.
121 x 697 x 421 x 628 x 869 = 19376693266964
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.
121 : 1, 11, 121
697 : 1, 17, 41, 697
421 : 1, 421
628 : 1, 2, 4, 157, 314, 628
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,697,421,628,869, is 1.
Now, the common factors can be found like this.
121:11x 11
697:17x 41
421:421
628:2x 2x 157
869:11x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 19376693266964/(1x11)
LCM = 19376693266964/11
LCM = 1761517569724
Thus, we can understand that the LCM of 121,697,421,628,869 is 1761517569724.
