HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 258, 669, 392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 258, 669, 392 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, 669, 392 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, 669, 392 is 1.
HCF(258, 669, 392) = 1
HCF of 258, 669, 392 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, 669, 392 is 1.
Highest Common Factor of 258,669,392 is 1
Step 1: Since 669 > 258, we apply the division lemma to 669 and 258, to get
669 = 258 x 2 + 153
Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 153 and 258, to get
258 = 153 x 1 + 105
Step 3: We consider the new divisor 153 and the new remainder 105, and apply the division lemma to get
153 = 105 x 1 + 48
We consider the new divisor 105 and the new remainder 48,and apply the division lemma to get
105 = 48 x 2 + 9
We consider the new divisor 48 and the new remainder 9,and apply the division lemma to get
48 = 9 x 5 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 258 and 669 is 3
Notice that 3 = HCF(9,3) = HCF(48,9) = HCF(105,48) = HCF(153,105) = HCF(258,153) = HCF(669,258) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 392 > 3, we apply the division lemma to 392 and 3, to get
392 = 3 x 130 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 392 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(392,3) .
