Given numbers are 782,791,278,147

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

The LCM of 782,791,278,147 is 1805582478.

Find LCM of 782,791,278,147 with Prime Factorization

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

2 x 7 x 391 x 113 x 139 x 21 = 1805582478

Therefore, the lowest common multiple of 782,791,278,147 is 1805582478.

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.

782 x 791 x 278 x 147 = 25278154692

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

791 : 1, 7, 113, 791

278 : 1, 2, 139, 278

147 : 1, 3, 7, 21, 49, 147

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,791,278,147, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

791:7x 113

278:2x 139

147:3x 7x 7

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 25278154692/(1x14)

LCM = 25278154692/14

LCM = 1805582478

Thus, we can understand that the LCM of 782,791,278,147 is 1805582478.
