HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 893, 396 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 893, 396 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 654, 893, 396 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 654, 893, 396 is 1.
HCF(654, 893, 396) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 893, 396 is 1.
Step 1: Since 893 > 654, we apply the division lemma to 893 and 654, to get
893 = 654 x 1 + 239
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 239 and 654, to get
654 = 239 x 2 + 176
Step 3: We consider the new divisor 239 and the new remainder 176, and apply the division lemma to get
239 = 176 x 1 + 63
We consider the new divisor 176 and the new remainder 63,and apply the division lemma to get
176 = 63 x 2 + 50
We consider the new divisor 63 and the new remainder 50,and apply the division lemma to get
63 = 50 x 1 + 13
We consider the new divisor 50 and the new remainder 13,and apply the division lemma to get
50 = 13 x 3 + 11
We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get
13 = 11 x 1 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 654 and 893 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(50,13) = HCF(63,50) = HCF(176,63) = HCF(239,176) = HCF(654,239) = HCF(893,654) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 396 > 1, we apply the division lemma to 396 and 1, to get
396 = 1 x 396 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 396 is 1
Notice that 1 = HCF(396,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
