HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 435, 185 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 843, 435, 185 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 843, 435, 185 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 843, 435, 185 is 1.
HCF(843, 435, 185) = 1
HCF of 843, 435, 185 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 843, 435, 185 is 1.
Highest Common Factor of 843,435,185 is 1
Step 1: Since 843 > 435, we apply the division lemma to 843 and 435, to get
843 = 435 x 1 + 408
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 408 and 435, to get
435 = 408 x 1 + 27
Step 3: We consider the new divisor 408 and the new remainder 27, and apply the division lemma to get
408 = 27 x 15 + 3
We consider the new divisor 27 and the new remainder 3, and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 843 and 435 is 3
Notice that 3 = HCF(27,3) = HCF(408,27) = HCF(435,408) = HCF(843,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 185 > 3, we apply the division lemma to 185 and 3, to get
185 = 3 x 61 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 185 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(185,3) .
