HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 230, 154, 697 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 230, 154, 697 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 230, 154, 697 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 230, 154, 697 is 1.
HCF(230, 154, 697) = 1
HCF of 230, 154, 697 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 230, 154, 697 is 1.
Highest Common Factor of 230,154,697 is 1
Step 1: Since 230 > 154, we apply the division lemma to 230 and 154, to get
230 = 154 x 1 + 76
Step 2: Since the reminder 154 ≠ 0, we apply division lemma to 76 and 154, to get
154 = 76 x 2 + 2
Step 3: We consider the new divisor 76 and the new remainder 2, and apply the division lemma to get
76 = 2 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 230 and 154 is 2
Notice that 2 = HCF(76,2) = HCF(154,76) = HCF(230,154) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 697 > 2, we apply the division lemma to 697 and 2, to get
697 = 2 x 348 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 697 is 1
Notice that 1 = HCF(2,1) = HCF(697,2) .
