HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 722, 427, 624 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 722, 427, 624 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 819, 722, 427, 624 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 819, 722, 427, 624 is 1.
HCF(819, 722, 427, 624) = 1
HCF of 819, 722, 427, 624 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 722, 427, 624 is 1.
Highest Common Factor of 819,722,427,624 is 1
Step 1: Since 819 > 722, we apply the division lemma to 819 and 722, to get
819 = 722 x 1 + 97
Step 2: Since the reminder 722 ≠ 0, we apply division lemma to 97 and 722, to get
722 = 97 x 7 + 43
Step 3: We consider the new divisor 97 and the new remainder 43, and apply the division lemma to get
97 = 43 x 2 + 11
We consider the new divisor 43 and the new remainder 11,and apply the division lemma to get
43 = 11 x 3 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 819 and 722 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(43,11) = HCF(97,43) = HCF(722,97) = HCF(819,722) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 427 > 1, we apply the division lemma to 427 and 1, to get
427 = 1 x 427 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 427 is 1
Notice that 1 = HCF(427,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 624 > 1, we apply the division lemma to 624 and 1, to get
624 = 1 x 624 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 624 is 1
Notice that 1 = HCF(624,1) .
