HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 659 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 830, 659 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 830, 659 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 830, 659 is 1.
HCF(830, 659) = 1
HCF of 830, 659 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 830, 659 is 1.
Highest Common Factor of 830,659 is 1
Step 1: Since 830 > 659, we apply the division lemma to 830 and 659, to get
830 = 659 x 1 + 171
Step 2: Since the reminder 659 ≠ 0, we apply division lemma to 171 and 659, to get
659 = 171 x 3 + 146
Step 3: We consider the new divisor 171 and the new remainder 146, and apply the division lemma to get
171 = 146 x 1 + 25
We consider the new divisor 146 and the new remainder 25,and apply the division lemma to get
146 = 25 x 5 + 21
We consider the new divisor 25 and the new remainder 21,and apply the division lemma to get
25 = 21 x 1 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 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 830 and 659 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(25,21) = HCF(146,25) = HCF(171,146) = HCF(659,171) = HCF(830,659) .
