HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1641, 400 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1641, 400 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 1641, 400 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 1641, 400 is 1.
HCF(1641, 400) = 1
HCF of 1641, 400 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1641, 400 is 1.
Highest Common Factor of 1641,400 is 1
Step 1: Since 1641 > 400, we apply the division lemma to 1641 and 400, to get
1641 = 400 x 4 + 41
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 41 and 400, to get
400 = 41 x 9 + 31
Step 3: We consider the new divisor 41 and the new remainder 31, and apply the division lemma to get
41 = 31 x 1 + 10
We consider the new divisor 31 and the new remainder 10,and apply the division lemma to get
31 = 10 x 3 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1641 and 400 is 1
Notice that 1 = HCF(10,1) = HCF(31,10) = HCF(41,31) = HCF(400,41) = HCF(1641,400) .
