HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 666, 851 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 905, 666, 851 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 905, 666, 851 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 905, 666, 851 is 1.
HCF(905, 666, 851) = 1
HCF of 905, 666, 851 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 905, 666, 851 is 1.
Highest Common Factor of 905,666,851 is 1
Step 1: Since 905 > 666, we apply the division lemma to 905 and 666, to get
905 = 666 x 1 + 239
Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 239 and 666, to get
666 = 239 x 2 + 188
Step 3: We consider the new divisor 239 and the new remainder 188, and apply the division lemma to get
239 = 188 x 1 + 51
We consider the new divisor 188 and the new remainder 51,and apply the division lemma to get
188 = 51 x 3 + 35
We consider the new divisor 51 and the new remainder 35,and apply the division lemma to get
51 = 35 x 1 + 16
We consider the new divisor 35 and the new remainder 16,and apply the division lemma to get
35 = 16 x 2 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 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 905 and 666 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(35,16) = HCF(51,35) = HCF(188,51) = HCF(239,188) = HCF(666,239) = HCF(905,666) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 851 > 1, we apply the division lemma to 851 and 1, to get
851 = 1 x 851 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 851 is 1
Notice that 1 = HCF(851,1) .
