HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 343, 121, 853, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 343, 121, 853, 31 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 343, 121, 853, 31 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 343, 121, 853, 31 is 1.

HCF(343, 121, 853, 31) = 1

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

HCF of:

Highest common factor (HCF) of 343, 121, 853, 31 is 1.

Highest Common Factor of 343,121,853,31 using Euclid's algorithm

Highest Common Factor of 343,121,853,31 is 1

Step 1: Since 343 > 121, we apply the division lemma to 343 and 121, to get

343 = 121 x 2 + 101

Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 101 and 121, to get

121 = 101 x 1 + 20

Step 3: We consider the new divisor 101 and the new remainder 20, and apply the division lemma to get

101 = 20 x 5 + 1

We consider the new divisor 20 and the new remainder 1, and apply the division lemma to get

20 = 1 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 343 and 121 is 1

Notice that 1 = HCF(20,1) = HCF(101,20) = HCF(121,101) = HCF(343,121) .


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

Step 1: Since 853 > 1, we apply the division lemma to 853 and 1, to get

853 = 1 x 853 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 853 is 1

Notice that 1 = HCF(853,1) .


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

Step 1: Since 31 > 1, we apply the division lemma to 31 and 1, to get

31 = 1 x 31 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 31 is 1

Notice that 1 = HCF(31,1) .
