HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 644, 947 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 644, 947 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 644, 947 is 1.
HCF(644, 947) = 1
HCF of 644, 947 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 644, 947 is 1.
Highest Common Factor of 644,947 is 1
Step 1: Since 947 > 644, we apply the division lemma to 947 and 644, to get
947 = 644 x 1 + 303
Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 303 and 644, to get
644 = 303 x 2 + 38
Step 3: We consider the new divisor 303 and the new remainder 38, and apply the division lemma to get
303 = 38 x 7 + 37
We consider the new divisor 38 and the new remainder 37,and apply the division lemma to get
38 = 37 x 1 + 1
We consider the new divisor 37 and the new remainder 1,and apply the division lemma to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 644 and 947 is 1
Notice that 1 = HCF(37,1) = HCF(38,37) = HCF(303,38) = HCF(644,303) = HCF(947,644) .
