HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 669, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 635, 669, 394 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 635, 669, 394 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 635, 669, 394 is 1.
HCF(635, 669, 394) = 1
HCF of 635, 669, 394 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 635, 669, 394 is 1.
Highest Common Factor of 635,669,394 is 1
Step 1: Since 669 > 635, we apply the division lemma to 669 and 635, to get
669 = 635 x 1 + 34
Step 2: Since the reminder 635 ≠ 0, we apply division lemma to 34 and 635, to get
635 = 34 x 18 + 23
Step 3: We consider the new divisor 34 and the new remainder 23, and apply the division lemma to get
34 = 23 x 1 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 635 and 669 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(635,34) = HCF(669,635) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get
394 = 1 x 394 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1
Notice that 1 = HCF(394,1) .
