HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 139, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 139, 864 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, 139, 864 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, 139, 864 is 1.
HCF(947, 139, 864) = 1
HCF of 947, 139, 864 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, 139, 864 is 1.
Highest Common Factor of 947,139,864 is 1
Step 1: Since 947 > 139, we apply the division lemma to 947 and 139, to get
947 = 139 x 6 + 113
Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 113 and 139, to get
139 = 113 x 1 + 26
Step 3: We consider the new divisor 113 and the new remainder 26, and apply the division lemma to get
113 = 26 x 4 + 9
We consider the new divisor 26 and the new remainder 9,and apply the division lemma to get
26 = 9 x 2 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 139 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(26,9) = HCF(113,26) = HCF(139,113) = HCF(947,139) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 1, we apply the division lemma to 864 and 1, to get
864 = 1 x 864 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 864 is 1
Notice that 1 = HCF(864,1) .
