HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 477, 862 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 666, 477, 862 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, 477, 862 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, 477, 862 is 1.
HCF(666, 477, 862) = 1
HCF of 666, 477, 862 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, 477, 862 is 1.
Highest Common Factor of 666,477,862 is 1
Step 1: Since 666 > 477, we apply the division lemma to 666 and 477, to get
666 = 477 x 1 + 189
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 189 and 477, to get
477 = 189 x 2 + 99
Step 3: We consider the new divisor 189 and the new remainder 99, and apply the division lemma to get
189 = 99 x 1 + 90
We consider the new divisor 99 and the new remainder 90,and apply the division lemma to get
99 = 90 x 1 + 9
We consider the new divisor 90 and the new remainder 9,and apply the division lemma to get
90 = 9 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 666 and 477 is 9
Notice that 9 = HCF(90,9) = HCF(99,90) = HCF(189,99) = HCF(477,189) = HCF(666,477) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 862 > 9, we apply the division lemma to 862 and 9, to get
862 = 9 x 95 + 7
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 7 and 9, to get
9 = 7 x 1 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 9 and 862 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(862,9) .
