HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 118 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 118 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, 118 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, 118 is 1.
HCF(641, 118) = 1
HCF of 641, 118 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, 118 is 1.
Highest Common Factor of 641,118 is 1
Step 1: Since 641 > 118, we apply the division lemma to 641 and 118, to get
641 = 118 x 5 + 51
Step 2: Since the reminder 118 ≠ 0, we apply division lemma to 51 and 118, to get
118 = 51 x 2 + 16
Step 3: We consider the new divisor 51 and the new remainder 16, and apply the division lemma to get
51 = 16 x 3 + 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 641 and 118 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(51,16) = HCF(118,51) = HCF(641,118) .
