HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 874, 123, 658 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 874, 123, 658 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 308, 874, 123, 658 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 308, 874, 123, 658 is 1.
HCF(308, 874, 123, 658) = 1
HCF of 308, 874, 123, 658 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 874, 123, 658 is 1.
Highest Common Factor of 308,874,123,658 is 1
Step 1: Since 874 > 308, we apply the division lemma to 874 and 308, to get
874 = 308 x 2 + 258
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 258 and 308, to get
308 = 258 x 1 + 50
Step 3: We consider the new divisor 258 and the new remainder 50, and apply the division lemma to get
258 = 50 x 5 + 8
We consider the new divisor 50 and the new remainder 8,and apply the division lemma to get
50 = 8 x 6 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 308 and 874 is 2
Notice that 2 = HCF(8,2) = HCF(50,8) = HCF(258,50) = HCF(308,258) = HCF(874,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 2, we apply the division lemma to 123 and 2, to get
123 = 2 x 61 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 123 is 1
Notice that 1 = HCF(2,1) = HCF(123,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 658 > 1, we apply the division lemma to 658 and 1, to get
658 = 1 x 658 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 658 is 1
Notice that 1 = HCF(658,1) .
