HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 508, 695 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 508, 695 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 508, 695 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 508, 695 is 1.
HCF(508, 695) = 1
HCF of 508, 695 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 508, 695 is 1.
Highest Common Factor of 508,695 is 1
Step 1: Since 695 > 508, we apply the division lemma to 695 and 508, to get
695 = 508 x 1 + 187
Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 187 and 508, to get
508 = 187 x 2 + 134
Step 3: We consider the new divisor 187 and the new remainder 134, and apply the division lemma to get
187 = 134 x 1 + 53
We consider the new divisor 134 and the new remainder 53,and apply the division lemma to get
134 = 53 x 2 + 28
We consider the new divisor 53 and the new remainder 28,and apply the division lemma to get
53 = 28 x 1 + 25
We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get
28 = 25 x 1 + 3
We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get
25 = 3 x 8 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 508 and 695 is 1
Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(53,28) = HCF(134,53) = HCF(187,134) = HCF(508,187) = HCF(695,508) .
