HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 291, 721 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 291, 721 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 498, 291, 721 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 498, 291, 721 is 1.
HCF(498, 291, 721) = 1
HCF of 498, 291, 721 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 291, 721 is 1.
Highest Common Factor of 498,291,721 is 1
Step 1: Since 498 > 291, we apply the division lemma to 498 and 291, to get
498 = 291 x 1 + 207
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 207 and 291, to get
291 = 207 x 1 + 84
Step 3: We consider the new divisor 207 and the new remainder 84, and apply the division lemma to get
207 = 84 x 2 + 39
We consider the new divisor 84 and the new remainder 39,and apply the division lemma to get
84 = 39 x 2 + 6
We consider the new divisor 39 and the new remainder 6,and apply the division lemma to get
39 = 6 x 6 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 498 and 291 is 3
Notice that 3 = HCF(6,3) = HCF(39,6) = HCF(84,39) = HCF(207,84) = HCF(291,207) = HCF(498,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 721 > 3, we apply the division lemma to 721 and 3, to get
721 = 3 x 240 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 721 is 1
Notice that 1 = HCF(3,1) = HCF(721,3) .
