HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 834, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 834, 655 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 834, 655 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 834, 655 is 1.
HCF(834, 655) = 1
HCF of 834, 655 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 834, 655 is 1.
Highest Common Factor of 834,655 is 1
Step 1: Since 834 > 655, we apply the division lemma to 834 and 655, to get
834 = 655 x 1 + 179
Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 179 and 655, to get
655 = 179 x 3 + 118
Step 3: We consider the new divisor 179 and the new remainder 118, and apply the division lemma to get
179 = 118 x 1 + 61
We consider the new divisor 118 and the new remainder 61,and apply the division lemma to get
118 = 61 x 1 + 57
We consider the new divisor 61 and the new remainder 57,and apply the division lemma to get
61 = 57 x 1 + 4
We consider the new divisor 57 and the new remainder 4,and apply the division lemma to get
57 = 4 x 14 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 834 and 655 is 1
Notice that 1 = HCF(4,1) = HCF(57,4) = HCF(61,57) = HCF(118,61) = HCF(179,118) = HCF(655,179) = HCF(834,655) .
