HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 122, 538, 187 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 520, 122, 538, 187 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 520, 122, 538, 187 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 520, 122, 538, 187 is 1.

HCF(520, 122, 538, 187) = 1

HCF of 520, 122, 538, 187 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 520, 122, 538, 187 is 1.

Highest Common Factor of 520,122,538,187 using Euclid's algorithm

Highest Common Factor of 520,122,538,187 is 1

Step 1: Since 520 > 122, we apply the division lemma to 520 and 122, to get

520 = 122 x 4 + 32

Step 2: Since the reminder 122 ≠ 0, we apply division lemma to 32 and 122, to get

122 = 32 x 3 + 26

Step 3: We consider the new divisor 32 and the new remainder 26, and apply the division lemma to get

32 = 26 x 1 + 6

We consider the new divisor 26 and the new remainder 6,and apply the division lemma to get

26 = 6 x 4 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 520 and 122 is 2

Notice that 2 = HCF(6,2) = HCF(26,6) = HCF(32,26) = HCF(122,32) = HCF(520,122) .


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

Step 1: Since 538 > 2, we apply the division lemma to 538 and 2, to get

538 = 2 x 269 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 538 is 2

Notice that 2 = HCF(538,2) .


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

Step 1: Since 187 > 2, we apply the division lemma to 187 and 2, to get

187 = 2 x 93 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 187 is 1

Notice that 1 = HCF(2,1) = HCF(187,2) .
