HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 133, 112 i.e. 7 the largest integer that leaves a remainder zero for all numbers.

HCF of 133, 112 is 7 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 133, 112 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 133, 112 is 7.

HCF(133, 112) = 7

## HCF of 133, 112 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 133, 112 is 7. ### Highest Common Factor of 133,112 is 7

Step 1: Since 133 > 112, we apply the division lemma to 133 and 112, to get

133 = 112 x 1 + 21

Step 2: Since the reminder 112 ≠ 0, we apply division lemma to 21 and 112, to get

112 = 21 x 5 + 7

Step 3: We consider the new divisor 21 and the new remainder 7, and apply the division lemma to get

21 = 7 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 133 and 112 is 7

Notice that 7 = HCF(21,7) = HCF(112,21) = HCF(133,112) .
