HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 910, 54 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 910, 54 is 2 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, 910, 54 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, 910, 54 is 2.
HCF(630, 910, 54) = 2
HCF of 630, 910, 54 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, 910, 54 is 2.
Highest Common Factor of 630,910,54 is 2
Step 1: Since 910 > 630, we apply the division lemma to 910 and 630, to get
910 = 630 x 1 + 280
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 280 and 630, to get
630 = 280 x 2 + 70
Step 3: We consider the new divisor 280 and the new remainder 70, and apply the division lemma to get
280 = 70 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 70, the HCF of 630 and 910 is 70
Notice that 70 = HCF(280,70) = HCF(630,280) = HCF(910,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 70 > 54, we apply the division lemma to 70 and 54, to get
70 = 54 x 1 + 16
Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 16 and 54, to get
54 = 16 x 3 + 6
Step 3: We consider the new divisor 16 and the new remainder 6, and apply the division lemma to get
16 = 6 x 2 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 70 and 54 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(54,16) = HCF(70,54) .
