HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 747, 140 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 989, 747, 140 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, 747, 140 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, 747, 140 is 1.
HCF(989, 747, 140) = 1
HCF of 989, 747, 140 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, 747, 140 is 1.
Highest Common Factor of 989,747,140 is 1
Step 1: Since 989 > 747, we apply the division lemma to 989 and 747, to get
989 = 747 x 1 + 242
Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 242 and 747, to get
747 = 242 x 3 + 21
Step 3: We consider the new divisor 242 and the new remainder 21, and apply the division lemma to get
242 = 21 x 11 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 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 989 and 747 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(242,21) = HCF(747,242) = HCF(989,747) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 140 > 1, we apply the division lemma to 140 and 1, to get
140 = 1 x 140 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 140 is 1
Notice that 1 = HCF(140,1) .
