HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 139, 897 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 139, 897 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 641, 139, 897 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 641, 139, 897 is 1.
HCF(641, 139, 897) = 1
HCF of 641, 139, 897 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 641, 139, 897 is 1.
Highest Common Factor of 641,139,897 is 1
Step 1: Since 641 > 139, we apply the division lemma to 641 and 139, to get
641 = 139 x 4 + 85
Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 85 and 139, to get
139 = 85 x 1 + 54
Step 3: We consider the new divisor 85 and the new remainder 54, and apply the division lemma to get
85 = 54 x 1 + 31
We consider the new divisor 54 and the new remainder 31,and apply the division lemma to get
54 = 31 x 1 + 23
We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 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 641 and 139 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(54,31) = HCF(85,54) = HCF(139,85) = HCF(641,139) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 897 > 1, we apply the division lemma to 897 and 1, to get
897 = 1 x 897 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 897 is 1
Notice that 1 = HCF(897,1) .
