HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 154 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 154 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 680, 154 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 680, 154 is 2.
HCF(680, 154) = 2
HCF of 680, 154 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 154 is 2.
Highest Common Factor of 680,154 is 2
Step 1: Since 680 > 154, we apply the division lemma to 680 and 154, to get
680 = 154 x 4 + 64
Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 64 and 154, to get
154 = 64 x 2 + 26
Step 3: We consider the new divisor 64 and the new remainder 26, and apply the division lemma to get
64 = 26 x 2 + 12
We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get
26 = 12 x 2 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 680 and 154 is 2
Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(64,26) = HCF(154,64) = HCF(680,154) .
