HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 988, 143, 492 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 988, 143, 492 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 988, 143, 492 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 988, 143, 492 is 1.
HCF(988, 143, 492) = 1
HCF of 988, 143, 492 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 988, 143, 492 is 1.
Highest Common Factor of 988,143,492 is 1
Step 1: Since 988 > 143, we apply the division lemma to 988 and 143, to get
988 = 143 x 6 + 130
Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 130 and 143, to get
143 = 130 x 1 + 13
Step 3: We consider the new divisor 130 and the new remainder 13, and apply the division lemma to get
130 = 13 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 988 and 143 is 13
Notice that 13 = HCF(130,13) = HCF(143,130) = HCF(988,143) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 492 > 13, we apply the division lemma to 492 and 13, to get
492 = 13 x 37 + 11
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 11 and 13, to get
13 = 11 x 1 + 2
Step 3: We consider the new divisor 11 and the new remainder 2, and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 13 and 492 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(492,13) .
