HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 843, 178, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 843, 178, 545 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 843, 178, 545 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 843, 178, 545 is 1.
HCF(843, 178, 545) = 1
HCF of 843, 178, 545 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 843, 178, 545 is 1.
Highest Common Factor of 843,178,545 is 1
Step 1: Since 843 > 178, we apply the division lemma to 843 and 178, to get
843 = 178 x 4 + 131
Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 131 and 178, to get
178 = 131 x 1 + 47
Step 3: We consider the new divisor 131 and the new remainder 47, and apply the division lemma to get
131 = 47 x 2 + 37
We consider the new divisor 47 and the new remainder 37,and apply the division lemma to get
47 = 37 x 1 + 10
We consider the new divisor 37 and the new remainder 10,and apply the division lemma to get
37 = 10 x 3 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 843 and 178 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(37,10) = HCF(47,37) = HCF(131,47) = HCF(178,131) = HCF(843,178) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 545 > 1, we apply the division lemma to 545 and 1, to get
545 = 1 x 545 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 545 is 1
Notice that 1 = HCF(545,1) .
