HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 445, 722, 244 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 445, 722, 244 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, 722, 244 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, 722, 244 is 1.
HCF(445, 722, 244) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 445, 722, 244 is 1.
Step 1: Since 722 > 445, we apply the division lemma to 722 and 445, to get
722 = 445 x 1 + 277
Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 277 and 445, to get
445 = 277 x 1 + 168
Step 3: We consider the new divisor 277 and the new remainder 168, and apply the division lemma to get
277 = 168 x 1 + 109
We consider the new divisor 168 and the new remainder 109,and apply the division lemma to get
168 = 109 x 1 + 59
We consider the new divisor 109 and the new remainder 59,and apply the division lemma to get
109 = 59 x 1 + 50
We consider the new divisor 59 and the new remainder 50,and apply the division lemma to get
59 = 50 x 1 + 9
We consider the new divisor 50 and the new remainder 9,and apply the division lemma to get
50 = 9 x 5 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 445 and 722 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(50,9) = HCF(59,50) = HCF(109,59) = HCF(168,109) = HCF(277,168) = HCF(445,277) = HCF(722,445) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 244 > 1, we apply the division lemma to 244 and 1, to get
244 = 1 x 244 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 244 is 1
Notice that 1 = HCF(244,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
