HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 988, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 988, 149 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, 149 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, 149 is 1.
HCF(988, 149) = 1
HCF of 988, 149 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, 149 is 1.
Highest Common Factor of 988,149 is 1
Step 1: Since 988 > 149, we apply the division lemma to 988 and 149, to get
988 = 149 x 6 + 94
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 94 and 149, to get
149 = 94 x 1 + 55
Step 3: We consider the new divisor 94 and the new remainder 55, and apply the division lemma to get
94 = 55 x 1 + 39
We consider the new divisor 55 and the new remainder 39,and apply the division lemma to get
55 = 39 x 1 + 16
We consider the new divisor 39 and the new remainder 16,and apply the division lemma to get
39 = 16 x 2 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 988 and 149 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(39,16) = HCF(55,39) = HCF(94,55) = HCF(149,94) = HCF(988,149) .
