HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 893, 385, 688, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 893, 385, 688, 12 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 893, 385, 688, 12 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 893, 385, 688, 12 is 1.
HCF(893, 385, 688, 12) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 893, 385, 688, 12 is 1.
Step 1: Since 893 > 385, we apply the division lemma to 893 and 385, to get
893 = 385 x 2 + 123
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 123 and 385, to get
385 = 123 x 3 + 16
Step 3: We consider the new divisor 123 and the new remainder 16, and apply the division lemma to get
123 = 16 x 7 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 893 and 385 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(123,16) = HCF(385,123) = HCF(893,385) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 688 > 1, we apply the division lemma to 688 and 1, to get
688 = 1 x 688 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 688 is 1
Notice that 1 = HCF(688,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
