Find LCM of 628,780,765,697 with Prime Factorization


2 628, 780, 765, 697
2 314, 390, 765, 697
3 157, 195, 765, 697
5 157, 65, 255, 697
17 157, 13, 51, 697
157, 13, 3, 41

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

2 x 2 x 3 x 5 x 17 x 157 x 13 x 3 x 41 = 256063860

Therefore, the lowest common multiple of 628,780,765,697 is 256063860.

LCM Formula to Find Lowest Common Multiple of 628,780,765,697

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.

628 x 780 x 765 x 697 = 261185137200

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.

628 : 1, 2, 4, 157, 314, 628

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,780,765,697, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

780:2x 2x 3x 5x 13

765:3x 3x 5x 17

697:17x 41

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

2x 2x 3x 5x 17 = 1020

Therefore, the value for common factors is 1020.

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 = 261185137200/(1x1020)

LCM = 261185137200/1020

LCM = 256063860

Thus, we can understand that the LCM of 628,780,765,697 is 256063860.
