HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 931 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 931 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 545, 931 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 545, 931 is 1.
HCF(545, 931) = 1
HCF of 545, 931 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 545, 931 is 1.
Highest Common Factor of 545,931 is 1
Step 1: Since 931 > 545, we apply the division lemma to 931 and 545, to get
931 = 545 x 1 + 386
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 386 and 545, to get
545 = 386 x 1 + 159
Step 3: We consider the new divisor 386 and the new remainder 159, and apply the division lemma to get
386 = 159 x 2 + 68
We consider the new divisor 159 and the new remainder 68,and apply the division lemma to get
159 = 68 x 2 + 23
We consider the new divisor 68 and the new remainder 23,and apply the division lemma to get
68 = 23 x 2 + 22
We consider the new divisor 23 and the new remainder 22,and apply the division lemma to get
23 = 22 x 1 + 1
We consider the new divisor 22 and the new remainder 1,and apply the division lemma to get
22 = 1 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 545 and 931 is 1
Notice that 1 = HCF(22,1) = HCF(23,22) = HCF(68,23) = HCF(159,68) = HCF(386,159) = HCF(545,386) = HCF(931,545) .
