Yes. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
False. 72 is a multiple of 6.
The greatest common factor is the highest number that divides exactly into two or more numbers. 16: 1, 2, 4, 8, 16 40: 1, 2, 4, 5, 8, 10, 20, 40 72: 1, 2, 3, 4, 6,8, 9, 12, 18, 24, 36, 72 The greatest common factor of 16, 40 and 72 is 8.
The highest common factor (HCF) of 40 and 72 is the largest number that divides both 40 and 72 without leaving a remainder. To find the HCF, we need to identify the common factors of 40 and 72, which are 1, 2, 4, and 8. The highest common factor of 40 and 72 is 8.
