HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 158, 440 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 158, 440 is 2 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 158, 440 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 158, 440 is 2.
HCF(158, 440) = 2
HCF of 158, 440 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 158, 440 is 2.
Highest Common Factor of 158,440 is 2
Step 1: Since 440 > 158, we apply the division lemma to 440 and 158, to get
440 = 158 x 2 + 124
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 124 and 158, to get
158 = 124 x 1 + 34
Step 3: We consider the new divisor 124 and the new remainder 34, and apply the division lemma to get
124 = 34 x 3 + 22
We consider the new divisor 34 and the new remainder 22,and apply the division lemma to get
34 = 22 x 1 + 12
We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get
22 = 12 x 1 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 158 and 440 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(34,22) = HCF(124,34) = HCF(158,124) = HCF(440,158) .
