HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 565, 800, 154 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 565, 800, 154 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 565, 800, 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 565, 800, 154 is 1.
HCF(565, 800, 154) = 1
HCF of 565, 800, 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 565, 800, 154 is 1.
Highest Common Factor of 565,800,154 is 1
Step 1: Since 800 > 565, we apply the division lemma to 800 and 565, to get
800 = 565 x 1 + 235
Step 2: Since the reminder 565 ≠ 0, we apply division lemma to 235 and 565, to get
565 = 235 x 2 + 95
Step 3: We consider the new divisor 235 and the new remainder 95, and apply the division lemma to get
235 = 95 x 2 + 45
We consider the new divisor 95 and the new remainder 45,and apply the division lemma to get
95 = 45 x 2 + 5
We consider the new divisor 45 and the new remainder 5,and apply the division lemma to get
45 = 5 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 565 and 800 is 5
Notice that 5 = HCF(45,5) = HCF(95,45) = HCF(235,95) = HCF(565,235) = HCF(800,565) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 154 > 5, we apply the division lemma to 154 and 5, to get
154 = 5 x 30 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: 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 5 and 154 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(154,5) .
