HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 498, 359, 307, 55 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 498, 359, 307, 55 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 498, 359, 307, 55 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 498, 359, 307, 55 is 1.
HCF(498, 359, 307, 55) = 1
HCF of 498, 359, 307, 55 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 498, 359, 307, 55 is 1.
Highest Common Factor of 498,359,307,55 is 1
Step 1: Since 498 > 359, we apply the division lemma to 498 and 359, to get
498 = 359 x 1 + 139
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 139 and 359, to get
359 = 139 x 2 + 81
Step 3: We consider the new divisor 139 and the new remainder 81, and apply the division lemma to get
139 = 81 x 1 + 58
We consider the new divisor 81 and the new remainder 58,and apply the division lemma to get
81 = 58 x 1 + 23
We consider the new divisor 58 and the new remainder 23,and apply the division lemma to get
58 = 23 x 2 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 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 498 and 359 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(58,23) = HCF(81,58) = HCF(139,81) = HCF(359,139) = HCF(498,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 307 > 1, we apply the division lemma to 307 and 1, to get
307 = 1 x 307 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 307 is 1
Notice that 1 = HCF(307,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 55 > 1, we apply the division lemma to 55 and 1, to get
55 = 1 x 55 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 55 is 1
Notice that 1 = HCF(55,1) .
