HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 306, 557, 498 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 306, 557, 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 306, 557, 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 306, 557, 498 is 1.
HCF(306, 557, 498) = 1
HCF of 306, 557, 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 306, 557, 498 is 1.
Highest Common Factor of 306,557,498 is 1
Step 1: Since 557 > 306, we apply the division lemma to 557 and 306, to get
557 = 306 x 1 + 251
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 251 and 306, to get
306 = 251 x 1 + 55
Step 3: We consider the new divisor 251 and the new remainder 55, and apply the division lemma to get
251 = 55 x 4 + 31
We consider the new divisor 55 and the new remainder 31,and apply the division lemma to get
55 = 31 x 1 + 24
We consider the new divisor 31 and the new remainder 24,and apply the division lemma to get
31 = 24 x 1 + 7
We consider the new divisor 24 and the new remainder 7,and apply the division lemma to get
24 = 7 x 3 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 306 and 557 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(24,7) = HCF(31,24) = HCF(55,31) = HCF(251,55) = HCF(306,251) = HCF(557,306) .
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) .
