HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 612, 433, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 612, 433, 661 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 612, 433, 661 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 612, 433, 661 is 1.
HCF(612, 433, 661) = 1
HCF of 612, 433, 661 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 612, 433, 661 is 1.
Highest Common Factor of 612,433,661 is 1
Step 1: Since 612 > 433, we apply the division lemma to 612 and 433, to get
612 = 433 x 1 + 179
Step 2: Since the reminder 433 ≠ 0, we apply division lemma to 179 and 433, to get
433 = 179 x 2 + 75
Step 3: We consider the new divisor 179 and the new remainder 75, and apply the division lemma to get
179 = 75 x 2 + 29
We consider the new divisor 75 and the new remainder 29,and apply the division lemma to get
75 = 29 x 2 + 17
We consider the new divisor 29 and the new remainder 17,and apply the division lemma to get
29 = 17 x 1 + 12
We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get
17 = 12 x 1 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 612 and 433 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(29,17) = HCF(75,29) = HCF(179,75) = HCF(433,179) = HCF(612,433) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 661 > 1, we apply the division lemma to 661 and 1, to get
661 = 1 x 661 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 661 is 1
Notice that 1 = HCF(661,1) .
