HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 258, 774, 659, 847 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 258, 774, 659, 847 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 258, 774, 659, 847 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 258, 774, 659, 847 is 1.
HCF(258, 774, 659, 847) = 1
HCF of 258, 774, 659, 847 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 258, 774, 659, 847 is 1.
Highest Common Factor of 258,774,659,847 is 1
Step 1: Since 774 > 258, we apply the division lemma to 774 and 258, to get
774 = 258 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 258, the HCF of 258 and 774 is 258
Notice that 258 = HCF(774,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 659 > 258, we apply the division lemma to 659 and 258, to get
659 = 258 x 2 + 143
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 143 and 258, to get
258 = 143 x 1 + 115
Step 3: We consider the new divisor 143 and the new remainder 115, and apply the division lemma to get
143 = 115 x 1 + 28
We consider the new divisor 115 and the new remainder 28,and apply the division lemma to get
115 = 28 x 4 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 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 258 and 659 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(115,28) = HCF(143,115) = HCF(258,143) = HCF(659,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 847 > 1, we apply the division lemma to 847 and 1, to get
847 = 1 x 847 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 847 is 1
Notice that 1 = HCF(847,1) .
