HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 246, 669, 325, 688 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 246, 669, 325, 688 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 246, 669, 325, 688 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 246, 669, 325, 688 is 1.
HCF(246, 669, 325, 688) = 1
HCF of 246, 669, 325, 688 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 246, 669, 325, 688 is 1.
Highest Common Factor of 246,669,325,688 is 1
Step 1: Since 669 > 246, we apply the division lemma to 669 and 246, to get
669 = 246 x 2 + 177
Step 2: Since the reminder 246 ≠ 0, we apply division lemma to 177 and 246, to get
246 = 177 x 1 + 69
Step 3: We consider the new divisor 177 and the new remainder 69, and apply the division lemma to get
177 = 69 x 2 + 39
We consider the new divisor 69 and the new remainder 39,and apply the division lemma to get
69 = 39 x 1 + 30
We consider the new divisor 39 and the new remainder 30,and apply the division lemma to get
39 = 30 x 1 + 9
We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get
30 = 9 x 3 + 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 246 and 669 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(39,30) = HCF(69,39) = HCF(177,69) = HCF(246,177) = HCF(669,246) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 325 > 3, we apply the division lemma to 325 and 3, to get
325 = 3 x 108 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 325 is 1
Notice that 1 = HCF(3,1) = HCF(325,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 688 > 1, we apply the division lemma to 688 and 1, to get
688 = 1 x 688 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 688 is 1
Notice that 1 = HCF(688,1) .
