The LCM is 140.
First we will find LCM for first two numbers (28 and 35).Step 1: Find the GCD (Greatest Common Divisor) of 28 and 35 which is 7.Step 2: Multiply the numbers 28 and 35 together (28 * 35 = 980)Step 3: Divide the 980 with 7. (980/7 = 140)So, the LCM of 28 and 35 is 140.Now we will find the LCM of above result (140) and third number (21) using the same procedure.The LCM of 28, 35 and 21 is 420.
The LCM is 35.
28 14,2 7,2,2 35 5,7 2 x 2 x 5 x 7 = 140, the LCM
The LCM is 35.
The LCM of 5 and 7 is 35. LCM stands for Least Common Multiple, or Lowest Common Multiple.
The LCM of 7 and 5 is 35 because 7 x 5 is 35 and 5 x 7 is 35, so 35 is the LCM
LCM(7, 5) = 35.
28 = 7 x 4, 35 = 7 x 5. They have 7 in common, so multiply 7 by the factors that are not common: 7 x 4 x 5 = 140
2 x 2 x 7 = 28 5 x 7 = 35 2 x 2 x 5 x 7 = 140, the LCM
To find the LCM of 28 and 5 you start by splitting these into their prime factors: 28 = 2x2x7 5 = 5 The next step would be to identify any common factors. In this case, there are none, and so we take all the factors, and multiply them together to find the LCM: 2x2x7x5 = 140 Thus the LCM of 28 and 5 is 140.
The LCM is 35. 5 x 7 = 35 7x 5 = 35
The LCM is 245.
