HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 545, 699, 799, 205 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 545, 699, 799, 205 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, 699, 799, 205 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, 699, 799, 205 is 1.
HCF(545, 699, 799, 205) = 1
HCF of 545, 699, 799, 205 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, 699, 799, 205 is 1.
Highest Common Factor of 545,699,799,205 is 1
Step 1: Since 699 > 545, we apply the division lemma to 699 and 545, to get
699 = 545 x 1 + 154
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 154 and 545, to get
545 = 154 x 3 + 83
Step 3: We consider the new divisor 154 and the new remainder 83, and apply the division lemma to get
154 = 83 x 1 + 71
We consider the new divisor 83 and the new remainder 71,and apply the division lemma to get
83 = 71 x 1 + 12
We consider the new divisor 71 and the new remainder 12,and apply the division lemma to get
71 = 12 x 5 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 545 and 699 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(71,12) = HCF(83,71) = HCF(154,83) = HCF(545,154) = HCF(699,545) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 799 > 1, we apply the division lemma to 799 and 1, to get
799 = 1 x 799 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 799 is 1
Notice that 1 = HCF(799,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 205 > 1, we apply the division lemma to 205 and 1, to get
205 = 1 x 205 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 205 is 1
Notice that 1 = HCF(205,1) .
