HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 947, 89, 322 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 947, 89, 322 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, 947, 89, 322 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, 947, 89, 322 is 1.
HCF(291, 947, 89, 322) = 1
HCF of 291, 947, 89, 322 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, 947, 89, 322 is 1.
Highest Common Factor of 291,947,89,322 is 1
Step 1: Since 947 > 291, we apply the division lemma to 947 and 291, to get
947 = 291 x 3 + 74
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 74 and 291, to get
291 = 74 x 3 + 69
Step 3: We consider the new divisor 74 and the new remainder 69, and apply the division lemma to get
74 = 69 x 1 + 5
We consider the new divisor 69 and the new remainder 5,and apply the division lemma to get
69 = 5 x 13 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 291 and 947 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(69,5) = HCF(74,69) = HCF(291,74) = HCF(947,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 1, we apply the division lemma to 89 and 1, to get
89 = 1 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 89 is 1
Notice that 1 = HCF(89,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 322 > 1, we apply the division lemma to 322 and 1, to get
322 = 1 x 322 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 322 is 1
Notice that 1 = HCF(322,1) .
