HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 181, 672, 520 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 181, 672, 520 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 181, 672, 520 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 181, 672, 520 is 1.
HCF(181, 672, 520) = 1
HCF of 181, 672, 520 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 181, 672, 520 is 1.
Highest Common Factor of 181,672,520 is 1
Step 1: Since 672 > 181, we apply the division lemma to 672 and 181, to get
672 = 181 x 3 + 129
Step 2: Since the reminder 181 ≠ 0, we apply division lemma to 129 and 181, to get
181 = 129 x 1 + 52
Step 3: We consider the new divisor 129 and the new remainder 52, and apply the division lemma to get
129 = 52 x 2 + 25
We consider the new divisor 52 and the new remainder 25,and apply the division lemma to get
52 = 25 x 2 + 2
We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get
25 = 2 x 12 + 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 181 and 672 is 1
Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(52,25) = HCF(129,52) = HCF(181,129) = HCF(672,181) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 520 > 1, we apply the division lemma to 520 and 1, to get
520 = 1 x 520 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 520 is 1
Notice that 1 = HCF(520,1) .
