HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 445, 9156 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 445, 9156 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 445, 9156 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 445, 9156 is 1.
HCF(445, 9156) = 1
HCF of 445, 9156 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 445, 9156 is 1.
Highest Common Factor of 445,9156 is 1
Step 1: Since 9156 > 445, we apply the division lemma to 9156 and 445, to get
9156 = 445 x 20 + 256
Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 256 and 445, to get
445 = 256 x 1 + 189
Step 3: We consider the new divisor 256 and the new remainder 189, and apply the division lemma to get
256 = 189 x 1 + 67
We consider the new divisor 189 and the new remainder 67,and apply the division lemma to get
189 = 67 x 2 + 55
We consider the new divisor 67 and the new remainder 55,and apply the division lemma to get
67 = 55 x 1 + 12
We consider the new divisor 55 and the new remainder 12,and apply the division lemma to get
55 = 12 x 4 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 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 445 and 9156 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(55,12) = HCF(67,55) = HCF(189,67) = HCF(256,189) = HCF(445,256) = HCF(9156,445) .
