HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 814, 759, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 814, 759, 643 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 622, 814, 759, 643 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 622, 814, 759, 643 is 1.
HCF(622, 814, 759, 643) = 1
HCF of 622, 814, 759, 643 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 814, 759, 643 is 1.
Highest Common Factor of 622,814,759,643 is 1
Step 1: Since 814 > 622, we apply the division lemma to 814 and 622, to get
814 = 622 x 1 + 192
Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 192 and 622, to get
622 = 192 x 3 + 46
Step 3: We consider the new divisor 192 and the new remainder 46, and apply the division lemma to get
192 = 46 x 4 + 8
We consider the new divisor 46 and the new remainder 8,and apply the division lemma to get
46 = 8 x 5 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 622 and 814 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(46,8) = HCF(192,46) = HCF(622,192) = HCF(814,622) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 759 > 2, we apply the division lemma to 759 and 2, to get
759 = 2 x 379 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 759 is 1
Notice that 1 = HCF(2,1) = HCF(759,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 643 > 1, we apply the division lemma to 643 and 1, to get
643 = 1 x 643 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 643 is 1
Notice that 1 = HCF(643,1) .
