HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 205 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 205 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, 205 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, 205 is 1.
HCF(947, 205) = 1
HCF of 947, 205 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, 205 is 1.
Highest Common Factor of 947,205 is 1
Step 1: Since 947 > 205, we apply the division lemma to 947 and 205, to get
947 = 205 x 4 + 127
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 127 and 205, to get
205 = 127 x 1 + 78
Step 3: We consider the new divisor 127 and the new remainder 78, and apply the division lemma to get
127 = 78 x 1 + 49
We consider the new divisor 78 and the new remainder 49,and apply the division lemma to get
78 = 49 x 1 + 29
We consider the new divisor 49 and the new remainder 29,and apply the division lemma to get
49 = 29 x 1 + 20
We consider the new divisor 29 and the new remainder 20,and apply the division lemma to get
29 = 20 x 1 + 9
We consider the new divisor 20 and the new remainder 9,and apply the division lemma to get
20 = 9 x 2 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 205 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(20,9) = HCF(29,20) = HCF(49,29) = HCF(78,49) = HCF(127,78) = HCF(205,127) = HCF(947,205) .
