HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 688 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 149, 688 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 149, 688 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 149, 688 is 1.
HCF(149, 688) = 1
HCF of 149, 688 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 149, 688 is 1.
Highest Common Factor of 149,688 is 1
Step 1: Since 688 > 149, we apply the division lemma to 688 and 149, to get
688 = 149 x 4 + 92
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 92 and 149, to get
149 = 92 x 1 + 57
Step 3: We consider the new divisor 92 and the new remainder 57, and apply the division lemma to get
92 = 57 x 1 + 35
We consider the new divisor 57 and the new remainder 35,and apply the division lemma to get
57 = 35 x 1 + 22
We consider the new divisor 35 and the new remainder 22,and apply the division lemma to get
35 = 22 x 1 + 13
We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get
22 = 13 x 1 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 688 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(35,22) = HCF(57,35) = HCF(92,57) = HCF(149,92) = HCF(688,149) .
