HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 340, 721, 40 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 340, 721, 40 is 1 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 340, 721, 40 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 340, 721, 40 is 1.

HCF(340, 721, 40) = 1

Highest Common Factor of 340,721,40 using Euclid's algorithm

Highest Common Factor of 340,721,40 is 1

Step 1: Since 721 > 340, we apply the division lemma to 721 and 340, to get

721 = 340 x 2 + 41

Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 41 and 340, to get

340 = 41 x 8 + 12

Step 3: We consider the new divisor 41 and the new remainder 12, and apply the division lemma to get

41 = 12 x 3 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 340 and 721 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(41,12) = HCF(340,41) = HCF(721,340) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 40 > 1, we apply the division lemma to 40 and 1, to get

40 = 1 x 40 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 40 is 1

Notice that 1 = HCF(40,1) .
