HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 631 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 947, 631 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 947, 631 is 1.
HCF(947, 631) = 1
HCF of 947, 631 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 947, 631 is 1.
Highest Common Factor of 947,631 is 1
Step 1: Since 947 > 631, we apply the division lemma to 947 and 631, to get
947 = 631 x 1 + 316
Step 2: Since the reminder 631 ≠ 0, we apply division lemma to 316 and 631, to get
631 = 316 x 1 + 315
Step 3: We consider the new divisor 316 and the new remainder 315, and apply the division lemma to get
316 = 315 x 1 + 1
We consider the new divisor 315 and the new remainder 1, and apply the division lemma to get
315 = 1 x 315 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 631 is 1
Notice that 1 = HCF(315,1) = HCF(316,315) = HCF(631,316) = HCF(947,631) .
