HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 695 i.e. 139 the largest integer that leaves a remainder zero for all numbers.
HCF of 417, 695 is 139 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 417, 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 417, 695 is 139.
HCF(417, 695) = 139
HCF of 417, 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 417, 695 is 139.
Highest Common Factor of 417,695 is 139
Step 1: Since 695 > 417, we apply the division lemma to 695 and 417, to get
695 = 417 x 1 + 278
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 278 and 417, to get
417 = 278 x 1 + 139
Step 3: We consider the new divisor 278 and the new remainder 139, and apply the division lemma to get
278 = 139 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 139, the HCF of 417 and 695 is 139
Notice that 139 = HCF(278,139) = HCF(417,278) = HCF(695,417) .
