HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 277 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 277 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, 277 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, 277 is 1.
HCF(630, 277) = 1
HCF of 630, 277 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, 277 is 1.
Highest Common Factor of 630,277 is 1
Step 1: Since 630 > 277, we apply the division lemma to 630 and 277, to get
630 = 277 x 2 + 76
Step 2: Since the reminder 277 ≠ 0, we apply division lemma to 76 and 277, to get
277 = 76 x 3 + 49
Step 3: We consider the new divisor 76 and the new remainder 49, and apply the division lemma to get
76 = 49 x 1 + 27
We consider the new divisor 49 and the new remainder 27,and apply the division lemma to get
49 = 27 x 1 + 22
We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 630 and 277 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(76,49) = HCF(277,76) = HCF(630,277) .
