HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 307, 498 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 307, 498 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 705, 307, 498 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 705, 307, 498 is 1.
HCF(705, 307, 498) = 1
HCF of 705, 307, 498 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 307, 498 is 1.
Highest Common Factor of 705,307,498 is 1
Step 1: Since 705 > 307, we apply the division lemma to 705 and 307, to get
705 = 307 x 2 + 91
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 91 and 307, to get
307 = 91 x 3 + 34
Step 3: We consider the new divisor 91 and the new remainder 34, and apply the division lemma to get
91 = 34 x 2 + 23
We consider the new divisor 34 and the new remainder 23,and apply the division lemma to get
34 = 23 x 1 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 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 705 and 307 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(91,34) = HCF(307,91) = HCF(705,307) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 498 > 1, we apply the division lemma to 498 and 1, to get
498 = 1 x 498 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 498 is 1
Notice that 1 = HCF(498,1) .
