The LCM of 4 and 15 is 60.
The least common multiple is the smallest number that is multiple of two or more numbers.
Multiples of 4: 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
Multiples of 15: 15, 30, 45, 60
The LCM of 4 and 15 is 60.
The LCM must include the highest amount of each prime factor in both numbers. The highest power of 2's is 2, of 3's is 1 and of 5's is 1.
So the LCM = 2 x 2 x 3 x 5 = 60
60 15x1=15 15x2=30 15x3=45 15x4=60
