HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 135, 680 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 135, 680 is 5 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 135, 680 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 135, 680 is 5.

HCF(135, 680) = 5

HCF of 135, 680 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 135, 680 is 5.

Highest Common Factor of 135,680 using Euclid's algorithm

Highest Common Factor of 135,680 is 5

Step 1: Since 680 > 135, we apply the division lemma to 680 and 135, to get

680 = 135 x 5 + 5

Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 5 and 135, to get

135 = 5 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 135 and 680 is 5

Notice that 5 = HCF(135,5) = HCF(680,135) .
