HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 385, 930 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 385, 930 is 5 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 605, 385, 930 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 605, 385, 930 is 5.
HCF(605, 385, 930) = 5
HCF of 605, 385, 930 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 385, 930 is 5.
Highest Common Factor of 605,385,930 is 5
Step 1: Since 605 > 385, we apply the division lemma to 605 and 385, to get
605 = 385 x 1 + 220
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 220 and 385, to get
385 = 220 x 1 + 165
Step 3: We consider the new divisor 220 and the new remainder 165, and apply the division lemma to get
220 = 165 x 1 + 55
We consider the new divisor 165 and the new remainder 55, and apply the division lemma to get
165 = 55 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 55, the HCF of 605 and 385 is 55
Notice that 55 = HCF(165,55) = HCF(220,165) = HCF(385,220) = HCF(605,385) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 930 > 55, we apply the division lemma to 930 and 55, to get
930 = 55 x 16 + 50
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 50 and 55, to get
55 = 50 x 1 + 5
Step 3: We consider the new divisor 50 and the new remainder 5, and apply the division lemma to get
50 = 5 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 55 and 930 is 5
Notice that 5 = HCF(50,5) = HCF(55,50) = HCF(930,55) .
