HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 549, 111, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 549, 111, 961 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 291, 549, 111, 961 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 291, 549, 111, 961 is 1.
HCF(291, 549, 111, 961) = 1
HCF of 291, 549, 111, 961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 291, 549, 111, 961 is 1.
Highest Common Factor of 291,549,111,961 is 1
Step 1: Since 549 > 291, we apply the division lemma to 549 and 291, to get
549 = 291 x 1 + 258
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 258 and 291, to get
291 = 258 x 1 + 33
Step 3: We consider the new divisor 258 and the new remainder 33, and apply the division lemma to get
258 = 33 x 7 + 27
We consider the new divisor 33 and the new remainder 27,and apply the division lemma to get
33 = 27 x 1 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 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 291 and 549 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(33,27) = HCF(258,33) = HCF(291,258) = HCF(549,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 111 > 3, we apply the division lemma to 111 and 3, to get
111 = 3 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 111 is 3
Notice that 3 = HCF(111,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 961 > 3, we apply the division lemma to 961 and 3, to get
961 = 3 x 320 + 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 961 is 1
Notice that 1 = HCF(3,1) = HCF(961,3) .
