HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 520, 178 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 520, 178 is 2 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, 178 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, 178 is 2.
HCF(520, 178) = 2
HCF of 520, 178 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 520, 178 is 2.
Highest Common Factor of 520,178 is 2
Step 1: Since 520 > 178, we apply the division lemma to 520 and 178, to get
520 = 178 x 2 + 164
Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 164 and 178, to get
178 = 164 x 1 + 14
Step 3: We consider the new divisor 164 and the new remainder 14, and apply the division lemma to get
164 = 14 x 11 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 520 and 178 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(164,14) = HCF(178,164) = HCF(520,178) .
