Find LCM of 780,936,695,156 with Prime Factorization
2 | 780, 936, 695, 156 |
2 | 390, 468, 695, 78 |
3 | 195, 234, 695, 39 |
5 | 65, 78, 695, 13 |
13 | 13, 78, 139, 13 |
1, 6, 139, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 1 x 6 x 139 x 1 = 650520
Therefore, the lowest common multiple of 780,936,695,156 is 650520.
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.
780 x 936 x 695 x 156 = 79155273600
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.
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
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
695 : 1, 5, 139, 695
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,936,695,156, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
936:2x 2x 2x 3x 3x 13
695:5x 139
156:2x 2x 3x 13
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 2x 2x 3x 3x 5x 13x 13 = 121680
Therefore, the value for common factors is 121680.
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 = 79155273600/(1x121680)
LCM = 79155273600/121680
LCM = 650520
Thus, we can understand that the LCM of 780,936,695,156 is 650520.
