HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 154, 446 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 154, 446 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 154, 446 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 154, 446 is 2.
HCF(154, 446) = 2
HCF of 154, 446 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 154, 446 is 2.
Highest Common Factor of 154,446 is 2
Step 1: Since 446 > 154, we apply the division lemma to 446 and 154, to get
446 = 154 x 2 + 138
Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 138 and 154, to get
154 = 138 x 1 + 16
Step 3: We consider the new divisor 138 and the new remainder 16, and apply the division lemma to get
138 = 16 x 8 + 10
We consider the new divisor 16 and the new remainder 10,and apply the division lemma to get
16 = 10 x 1 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 154 and 446 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(138,16) = HCF(154,138) = HCF(446,154) .
