HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 3396, 4705 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 3396, 4705 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, 3396, 4705 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, 3396, 4705 is 1.
HCF(947, 3396, 4705) = 1
HCF of 947, 3396, 4705 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, 3396, 4705 is 1.
Highest Common Factor of 947,3396,4705 is 1
Step 1: Since 3396 > 947, we apply the division lemma to 3396 and 947, to get
3396 = 947 x 3 + 555
Step 2: Since the reminder 947 ≠ 0, we apply division lemma to 555 and 947, to get
947 = 555 x 1 + 392
Step 3: We consider the new divisor 555 and the new remainder 392, and apply the division lemma to get
555 = 392 x 1 + 163
We consider the new divisor 392 and the new remainder 163,and apply the division lemma to get
392 = 163 x 2 + 66
We consider the new divisor 163 and the new remainder 66,and apply the division lemma to get
163 = 66 x 2 + 31
We consider the new divisor 66 and the new remainder 31,and apply the division lemma to get
66 = 31 x 2 + 4
We consider the new divisor 31 and the new remainder 4,and apply the division lemma to get
31 = 4 x 7 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 3396 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(66,31) = HCF(163,66) = HCF(392,163) = HCF(555,392) = HCF(947,555) = HCF(3396,947) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4705 > 1, we apply the division lemma to 4705 and 1, to get
4705 = 1 x 4705 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4705 is 1
Notice that 1 = HCF(4705,1) .
