HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 879, 778, 638 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 530, 879, 778, 638 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 530, 879, 778, 638 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 530, 879, 778, 638 is 1.
HCF(530, 879, 778, 638) = 1
HCF of 530, 879, 778, 638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 530, 879, 778, 638 is 1.
Highest Common Factor of 530,879,778,638 is 1
Step 1: Since 879 > 530, we apply the division lemma to 879 and 530, to get
879 = 530 x 1 + 349
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 349 and 530, to get
530 = 349 x 1 + 181
Step 3: We consider the new divisor 349 and the new remainder 181, and apply the division lemma to get
349 = 181 x 1 + 168
We consider the new divisor 181 and the new remainder 168,and apply the division lemma to get
181 = 168 x 1 + 13
We consider the new divisor 168 and the new remainder 13,and apply the division lemma to get
168 = 13 x 12 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 530 and 879 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(168,13) = HCF(181,168) = HCF(349,181) = HCF(530,349) = HCF(879,530) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 1, we apply the division lemma to 778 and 1, to get
778 = 1 x 778 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 778 is 1
Notice that 1 = HCF(778,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 638 > 1, we apply the division lemma to 638 and 1, to get
638 = 1 x 638 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 638 is 1
Notice that 1 = HCF(638,1) .
