HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 206 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 206 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, 206 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, 206 is 1.
HCF(947, 206) = 1
HCF of 947, 206 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, 206 is 1.
Highest Common Factor of 947,206 is 1
Step 1: Since 947 > 206, we apply the division lemma to 947 and 206, to get
947 = 206 x 4 + 123
Step 2: Since the reminder 206 ≠ 0, we apply division lemma to 123 and 206, to get
206 = 123 x 1 + 83
Step 3: We consider the new divisor 123 and the new remainder 83, and apply the division lemma to get
123 = 83 x 1 + 40
We consider the new divisor 83 and the new remainder 40,and apply the division lemma to get
83 = 40 x 2 + 3
We consider the new divisor 40 and the new remainder 3,and apply the division lemma to get
40 = 3 x 13 + 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 947 and 206 is 1
Notice that 1 = HCF(3,1) = HCF(40,3) = HCF(83,40) = HCF(123,83) = HCF(206,123) = HCF(947,206) .
