HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 340, 1872 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 340, 1872 is 4 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 340, 1872 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 340, 1872 is 4.
HCF(340, 1872) = 4
HCF of 340, 1872 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 340, 1872 is 4.
Highest Common Factor of 340,1872 is 4
Step 1: Since 1872 > 340, we apply the division lemma to 1872 and 340, to get
1872 = 340 x 5 + 172
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 172 and 340, to get
340 = 172 x 1 + 168
Step 3: We consider the new divisor 172 and the new remainder 168, and apply the division lemma to get
172 = 168 x 1 + 4
We consider the new divisor 168 and the new remainder 4, and apply the division lemma to get
168 = 4 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 340 and 1872 is 4
Notice that 4 = HCF(168,4) = HCF(172,168) = HCF(340,172) = HCF(1872,340) .
