HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 486, 802, 633 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 400, 486, 802, 633 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 400, 486, 802, 633 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 400, 486, 802, 633 is 1.
HCF(400, 486, 802, 633) = 1
HCF of 400, 486, 802, 633 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 400, 486, 802, 633 is 1.
Highest Common Factor of 400,486,802,633 is 1
Step 1: Since 486 > 400, we apply the division lemma to 486 and 400, to get
486 = 400 x 1 + 86
Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 86 and 400, to get
400 = 86 x 4 + 56
Step 3: We consider the new divisor 86 and the new remainder 56, and apply the division lemma to get
86 = 56 x 1 + 30
We consider the new divisor 56 and the new remainder 30,and apply the division lemma to get
56 = 30 x 1 + 26
We consider the new divisor 30 and the new remainder 26,and apply the division lemma to get
30 = 26 x 1 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 400 and 486 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(30,26) = HCF(56,30) = HCF(86,56) = HCF(400,86) = HCF(486,400) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 2, we apply the division lemma to 802 and 2, to get
802 = 2 x 401 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 802 is 2
Notice that 2 = HCF(802,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 633 > 2, we apply the division lemma to 633 and 2, to get
633 = 2 x 316 + 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 633 is 1
Notice that 1 = HCF(2,1) = HCF(633,2) .
