HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 477, 721, 954 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 698, 477, 721, 954 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 698, 477, 721, 954 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 698, 477, 721, 954 is 1.
HCF(698, 477, 721, 954) = 1
HCF of 698, 477, 721, 954 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 698, 477, 721, 954 is 1.
Highest Common Factor of 698,477,721,954 is 1
Step 1: Since 698 > 477, we apply the division lemma to 698 and 477, to get
698 = 477 x 1 + 221
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 221 and 477, to get
477 = 221 x 2 + 35
Step 3: We consider the new divisor 221 and the new remainder 35, and apply the division lemma to get
221 = 35 x 6 + 11
We consider the new divisor 35 and the new remainder 11,and apply the division lemma to get
35 = 11 x 3 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 698 and 477 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(35,11) = HCF(221,35) = HCF(477,221) = HCF(698,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 721 > 1, we apply the division lemma to 721 and 1, to get
721 = 1 x 721 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 721 is 1
Notice that 1 = HCF(721,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 954 > 1, we apply the division lemma to 954 and 1, to get
954 = 1 x 954 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 954 is 1
Notice that 1 = HCF(954,1) .
