HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 63, 177 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 480, 63, 177 is 3 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 480, 63, 177 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 480, 63, 177 is 3.
HCF(480, 63, 177) = 3
HCF of 480, 63, 177 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 480, 63, 177 is 3.
Highest Common Factor of 480,63,177 is 3
Step 1: Since 480 > 63, we apply the division lemma to 480 and 63, to get
480 = 63 x 7 + 39
Step 2: Since the reminder 63 ≠ 0, we apply division lemma to 39 and 63, to get
63 = 39 x 1 + 24
Step 3: We consider the new divisor 39 and the new remainder 24, and apply the division lemma to get
39 = 24 x 1 + 15
We consider the new divisor 24 and the new remainder 15,and apply the division lemma to get
24 = 15 x 1 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 480 and 63 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(24,15) = HCF(39,24) = HCF(63,39) = HCF(480,63) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 177 > 3, we apply the division lemma to 177 and 3, to get
177 = 3 x 59 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 177 is 3
Notice that 3 = HCF(177,3) .
