HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 425, 164 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 425, 164 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 778, 425, 164 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 778, 425, 164 is 1.
HCF(778, 425, 164) = 1
HCF of 778, 425, 164 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 778, 425, 164 is 1.
Highest Common Factor of 778,425,164 is 1
Step 1: Since 778 > 425, we apply the division lemma to 778 and 425, to get
778 = 425 x 1 + 353
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 353 and 425, to get
425 = 353 x 1 + 72
Step 3: We consider the new divisor 353 and the new remainder 72, and apply the division lemma to get
353 = 72 x 4 + 65
We consider the new divisor 72 and the new remainder 65,and apply the division lemma to get
72 = 65 x 1 + 7
We consider the new divisor 65 and the new remainder 7,and apply the division lemma to get
65 = 7 x 9 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 778 and 425 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(65,7) = HCF(72,65) = HCF(353,72) = HCF(425,353) = HCF(778,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 164 > 1, we apply the division lemma to 164 and 1, to get
164 = 1 x 164 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 164 is 1
Notice that 1 = HCF(164,1) .
