What is the LCM of 64and 72?
To calculate the LCM, you first have to split the numbers up into their prime factors: 64 = 2x2x2x2x2x2 72 = 2x2x2x3x3 The next step is to calculate the HCF. In this case it will be 2x2x2 = 8. Finally, you multiply the two numbers and divide by the HCF: 64x72/8 = 576 And therefore the LCM of 64 and 72 is 576.
