HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 794, 168 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 794, 168 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 425, 794, 168 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 425, 794, 168 is 1.
HCF(425, 794, 168) = 1
HCF of 425, 794, 168 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 794, 168 is 1.
Highest Common Factor of 425,794,168 is 1
Step 1: Since 794 > 425, we apply the division lemma to 794 and 425, to get
794 = 425 x 1 + 369
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 369 and 425, to get
425 = 369 x 1 + 56
Step 3: We consider the new divisor 369 and the new remainder 56, and apply the division lemma to get
369 = 56 x 6 + 33
We consider the new divisor 56 and the new remainder 33,and apply the division lemma to get
56 = 33 x 1 + 23
We consider the new divisor 33 and the new remainder 23,and apply the division lemma to get
33 = 23 x 1 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 425 and 794 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(33,23) = HCF(56,33) = HCF(369,56) = HCF(425,369) = HCF(794,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 168 > 1, we apply the division lemma to 168 and 1, to get
168 = 1 x 168 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 168 is 1
Notice that 1 = HCF(168,1) .
