HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 702, 381, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 702, 381, 694 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 702, 381, 694 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 702, 381, 694 is 1.
HCF(702, 381, 694) = 1
HCF of 702, 381, 694 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 702, 381, 694 is 1.
Highest Common Factor of 702,381,694 is 1
Step 1: Since 702 > 381, we apply the division lemma to 702 and 381, to get
702 = 381 x 1 + 321
Step 2: Since the reminder 381 ≠ 0, we apply division lemma to 321 and 381, to get
381 = 321 x 1 + 60
Step 3: We consider the new divisor 321 and the new remainder 60, and apply the division lemma to get
321 = 60 x 5 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 702 and 381 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(321,60) = HCF(381,321) = HCF(702,381) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 694 > 3, we apply the division lemma to 694 and 3, to get
694 = 3 x 231 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 694 is 1
Notice that 1 = HCF(3,1) = HCF(694,3) .
