HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 385, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 385, 802 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 486, 385, 802 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 486, 385, 802 is 1.
HCF(486, 385, 802) = 1
HCF of 486, 385, 802 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 385, 802 is 1.
Highest Common Factor of 486,385,802 is 1
Step 1: Since 486 > 385, we apply the division lemma to 486 and 385, to get
486 = 385 x 1 + 101
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 101 and 385, to get
385 = 101 x 3 + 82
Step 3: We consider the new divisor 101 and the new remainder 82, and apply the division lemma to get
101 = 82 x 1 + 19
We consider the new divisor 82 and the new remainder 19,and apply the division lemma to get
82 = 19 x 4 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 486 and 385 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(82,19) = HCF(101,82) = HCF(385,101) = HCF(486,385) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 1, we apply the division lemma to 802 and 1, to get
802 = 1 x 802 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 802 is 1
Notice that 1 = HCF(802,1) .
