HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 629, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 629, 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 989, 629, 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 989, 629, 694 is 1.
HCF(989, 629, 694) = 1
HCF of 989, 629, 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 989, 629, 694 is 1.
Highest Common Factor of 989,629,694 is 1
Step 1: Since 989 > 629, we apply the division lemma to 989 and 629, to get
989 = 629 x 1 + 360
Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 360 and 629, to get
629 = 360 x 1 + 269
Step 3: We consider the new divisor 360 and the new remainder 269, and apply the division lemma to get
360 = 269 x 1 + 91
We consider the new divisor 269 and the new remainder 91,and apply the division lemma to get
269 = 91 x 2 + 87
We consider the new divisor 91 and the new remainder 87,and apply the division lemma to get
91 = 87 x 1 + 4
We consider the new divisor 87 and the new remainder 4,and apply the division lemma to get
87 = 4 x 21 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma 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 989 and 629 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(87,4) = HCF(91,87) = HCF(269,91) = HCF(360,269) = HCF(629,360) = HCF(989,629) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 694 > 1, we apply the division lemma to 694 and 1, to get
694 = 1 x 694 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 694 is 1
Notice that 1 = HCF(694,1) .
