HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 994 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 994 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, 994 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, 994 is 1.
HCF(545, 994) = 1
HCF of 545, 994 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, 994 is 1.
Highest Common Factor of 545,994 is 1
Step 1: Since 994 > 545, we apply the division lemma to 994 and 545, to get
994 = 545 x 1 + 449
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 449 and 545, to get
545 = 449 x 1 + 96
Step 3: We consider the new divisor 449 and the new remainder 96, and apply the division lemma to get
449 = 96 x 4 + 65
We consider the new divisor 96 and the new remainder 65,and apply the division lemma to get
96 = 65 x 1 + 31
We consider the new divisor 65 and the new remainder 31,and apply the division lemma to get
65 = 31 x 2 + 3
We consider the new divisor 31 and the new remainder 3,and apply the division lemma to get
31 = 3 x 10 + 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 545 and 994 is 1
Notice that 1 = HCF(3,1) = HCF(31,3) = HCF(65,31) = HCF(96,65) = HCF(449,96) = HCF(545,449) = HCF(994,545) .
