HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 905, 112 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 905, 112 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 855, 905, 112 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 855, 905, 112 is 1.
HCF(855, 905, 112) = 1
HCF of 855, 905, 112 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 855, 905, 112 is 1.
Highest Common Factor of 855,905,112 is 1
Step 1: Since 905 > 855, we apply the division lemma to 905 and 855, to get
905 = 855 x 1 + 50
Step 2: Since the reminder 855 ≠ 0, we apply division lemma to 50 and 855, to get
855 = 50 x 17 + 5
Step 3: We consider the new divisor 50 and the new remainder 5, and apply the division lemma to get
50 = 5 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 855 and 905 is 5
Notice that 5 = HCF(50,5) = HCF(855,50) = HCF(905,855) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 112 > 5, we apply the division lemma to 112 and 5, to get
112 = 5 x 22 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 112 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(112,5) .
