HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 164, 781, 854 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 164, 781, 854 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 164, 781, 854 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 164, 781, 854 is 1.
HCF(164, 781, 854) = 1
HCF of 164, 781, 854 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 164, 781, 854 is 1.
Highest Common Factor of 164,781,854 is 1
Step 1: Since 781 > 164, we apply the division lemma to 781 and 164, to get
781 = 164 x 4 + 125
Step 2: Since the reminder 164 ≠ 0, we apply division lemma to 125 and 164, to get
164 = 125 x 1 + 39
Step 3: We consider the new divisor 125 and the new remainder 39, and apply the division lemma to get
125 = 39 x 3 + 8
We consider the new divisor 39 and the new remainder 8,and apply the division lemma to get
39 = 8 x 4 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 164 and 781 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(39,8) = HCF(125,39) = HCF(164,125) = HCF(781,164) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 854 > 1, we apply the division lemma to 854 and 1, to get
854 = 1 x 854 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 854 is 1
Notice that 1 = HCF(854,1) .
