HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 177, 488 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 177, 488 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 630, 177, 488 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 630, 177, 488 is 1.
HCF(630, 177, 488) = 1
HCF of 630, 177, 488 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 177, 488 is 1.
Highest Common Factor of 630,177,488 is 1
Step 1: Since 630 > 177, we apply the division lemma to 630 and 177, to get
630 = 177 x 3 + 99
Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 99 and 177, to get
177 = 99 x 1 + 78
Step 3: We consider the new divisor 99 and the new remainder 78, and apply the division lemma to get
99 = 78 x 1 + 21
We consider the new divisor 78 and the new remainder 21,and apply the division lemma to get
78 = 21 x 3 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 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 630 and 177 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(78,21) = HCF(99,78) = HCF(177,99) = HCF(630,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 488 > 3, we apply the division lemma to 488 and 3, to get
488 = 3 x 162 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 488 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(488,3) .
