Given numbers are 49,56,19,97,779

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 49,56,19,97,779 is 29620696.

Find LCM of 49,56,19,97,779 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

7 x 19 x 7 x 8 x 1 x 97 x 41 = 29620696

Therefore, the lowest common multiple of 49,56,19,97,779 is 29620696.

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.

49 x 56 x 19 x 97 x 779 = 3939552568

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.

49 : 1, 7, 49

56 : 1, 2, 4, 7, 8, 14, 28, 56

19 : 1, 19

97 : 1, 97

779 : 1, 19, 41, 779

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 49,56,19,97,779, is 1.

Now, the common factors can be found like this.

49:7x 7

56:2x 2x 2x 7

19:19

97:97

779:19x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 3939552568/(1x133)

LCM = 3939552568/133

LCM = 29620696

Thus, we can understand that the LCM of 49,56,19,97,779 is 29620696.
