HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 913, 38720 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 913, 38720 is 11 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 913, 38720 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 913, 38720 is 11.
HCF(913, 38720) = 11
HCF of 913, 38720 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 913, 38720 is 11.
Highest Common Factor of 913,38720 is 11
Step 1: Since 38720 > 913, we apply the division lemma to 38720 and 913, to get
38720 = 913 x 42 + 374
Step 2: Since the reminder 913 ≠ 0, we apply division lemma to 374 and 913, to get
913 = 374 x 2 + 165
Step 3: We consider the new divisor 374 and the new remainder 165, and apply the division lemma to get
374 = 165 x 2 + 44
We consider the new divisor 165 and the new remainder 44,and apply the division lemma to get
165 = 44 x 3 + 33
We consider the new divisor 44 and the new remainder 33,and apply the division lemma to get
44 = 33 x 1 + 11
We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 913 and 38720 is 11
Notice that 11 = HCF(33,11) = HCF(44,33) = HCF(165,44) = HCF(374,165) = HCF(913,374) = HCF(38720,913) .
