HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 874, 630, 278, 816 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 874, 630, 278, 816 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 874, 630, 278, 816 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 874, 630, 278, 816 is 2.
HCF(874, 630, 278, 816) = 2
HCF of 874, 630, 278, 816 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 874, 630, 278, 816 is 2.
Highest Common Factor of 874,630,278,816 is 2
Step 1: Since 874 > 630, we apply the division lemma to 874 and 630, to get
874 = 630 x 1 + 244
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 244 and 630, to get
630 = 244 x 2 + 142
Step 3: We consider the new divisor 244 and the new remainder 142, and apply the division lemma to get
244 = 142 x 1 + 102
We consider the new divisor 142 and the new remainder 102,and apply the division lemma to get
142 = 102 x 1 + 40
We consider the new divisor 102 and the new remainder 40,and apply the division lemma to get
102 = 40 x 2 + 22
We consider the new divisor 40 and the new remainder 22,and apply the division lemma to get
40 = 22 x 1 + 18
We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get
22 = 18 x 1 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 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 874 and 630 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(40,22) = HCF(102,40) = HCF(142,102) = HCF(244,142) = HCF(630,244) = HCF(874,630) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 278 > 2, we apply the division lemma to 278 and 2, to get
278 = 2 x 139 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 278 is 2
Notice that 2 = HCF(278,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 2, we apply the division lemma to 816 and 2, to get
816 = 2 x 408 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 816 is 2
Notice that 2 = HCF(816,2) .
