HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 870, 499 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 666, 870, 499 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 666, 870, 499 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 666, 870, 499 is 1.
HCF(666, 870, 499) = 1
HCF of 666, 870, 499 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 666, 870, 499 is 1.
Highest Common Factor of 666,870,499 is 1
Step 1: Since 870 > 666, we apply the division lemma to 870 and 666, to get
870 = 666 x 1 + 204
Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 204 and 666, to get
666 = 204 x 3 + 54
Step 3: We consider the new divisor 204 and the new remainder 54, and apply the division lemma to get
204 = 54 x 3 + 42
We consider the new divisor 54 and the new remainder 42,and apply the division lemma to get
54 = 42 x 1 + 12
We consider the new divisor 42 and the new remainder 12,and apply the division lemma to get
42 = 12 x 3 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 666 and 870 is 6
Notice that 6 = HCF(12,6) = HCF(42,12) = HCF(54,42) = HCF(204,54) = HCF(666,204) = HCF(870,666) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 499 > 6, we apply the division lemma to 499 and 6, to get
499 = 6 x 83 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, 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 6 and 499 is 1
Notice that 1 = HCF(6,1) = HCF(499,6) .
