HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 696, 868, 570, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 696, 868, 570, 451 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 696, 868, 570, 451 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 696, 868, 570, 451 is 1.
HCF(696, 868, 570, 451) = 1
HCF of 696, 868, 570, 451 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 696, 868, 570, 451 is 1.
Highest Common Factor of 696,868,570,451 is 1
Step 1: Since 868 > 696, we apply the division lemma to 868 and 696, to get
868 = 696 x 1 + 172
Step 2: Since the reminder 696 ≠ 0, we apply division lemma to 172 and 696, to get
696 = 172 x 4 + 8
Step 3: We consider the new divisor 172 and the new remainder 8, and apply the division lemma to get
172 = 8 x 21 + 4
We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 696 and 868 is 4
Notice that 4 = HCF(8,4) = HCF(172,8) = HCF(696,172) = HCF(868,696) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 570 > 4, we apply the division lemma to 570 and 4, to get
570 = 4 x 142 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 570 is 2
Notice that 2 = HCF(4,2) = HCF(570,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 451 > 2, we apply the division lemma to 451 and 2, to get
451 = 2 x 225 + 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 451 is 1
Notice that 1 = HCF(2,1) = HCF(451,2) .
