HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 84, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 84, 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 354, 84, 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 354, 84, 947 is 1.
HCF(354, 84, 947) = 1
HCF of 354, 84, 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 354, 84, 947 is 1.
Highest Common Factor of 354,84,947 is 1
Step 1: Since 354 > 84, we apply the division lemma to 354 and 84, to get
354 = 84 x 4 + 18
Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 18 and 84, to get
84 = 18 x 4 + 12
Step 3: We consider the new divisor 18 and the new remainder 12, and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6, and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 354 and 84 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(84,18) = HCF(354,84) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 947 > 6, we apply the division lemma to 947 and 6, to get
947 = 6 x 157 + 5
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get
6 = 5 x 1 + 1
Step 3: We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 947 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(947,6) .
