Given numbers are 775,455,253,742

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

The LCM of 775,455,253,742 is 1891339450.

Find LCM of 775,455,253,742 with Prime Factorization

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

5 x 7 x 155 x 13 x 253 x 106 = 1891339450

Therefore, the lowest common multiple of 775,455,253,742 is 1891339450.

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.

775 x 455 x 253 x 742 = 66196880750

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.

775 : 1, 5, 25, 31, 155, 775

455 : 1, 5, 7, 13, 35, 65, 91, 455

253 : 1, 11, 23, 253

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,455,253,742, is 1.

Now, the common factors can be found like this.

775:5x 5x 31

455:5x 7x 13

253:11x 23

742:2x 7x 53

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

5x 7 = 35

Therefore, the value for common factors is 35.

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 = 66196880750/(1x35)

LCM = 66196880750/35

LCM = 1891339450

Thus, we can understand that the LCM of 775,455,253,742 is 1891339450.
