HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 159, 851, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 159, 851, 641 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 159, 851, 641 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 159, 851, 641 is 1.
HCF(159, 851, 641) = 1
HCF of 159, 851, 641 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 159, 851, 641 is 1.
Highest Common Factor of 159,851,641 is 1
Step 1: Since 851 > 159, we apply the division lemma to 851 and 159, to get
851 = 159 x 5 + 56
Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 56 and 159, to get
159 = 56 x 2 + 47
Step 3: We consider the new divisor 56 and the new remainder 47, and apply the division lemma to get
56 = 47 x 1 + 9
We consider the new divisor 47 and the new remainder 9,and apply the division lemma to get
47 = 9 x 5 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 159 and 851 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(47,9) = HCF(56,47) = HCF(159,56) = HCF(851,159) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 641 > 1, we apply the division lemma to 641 and 1, to get
641 = 1 x 641 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 641 is 1
Notice that 1 = HCF(641,1) .
