HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 384, 492, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 384, 492, 655 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 384, 492, 655 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 384, 492, 655 is 1.
HCF(384, 492, 655) = 1
HCF of 384, 492, 655 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 384, 492, 655 is 1.
Highest Common Factor of 384,492,655 is 1
Step 1: Since 492 > 384, we apply the division lemma to 492 and 384, to get
492 = 384 x 1 + 108
Step 2: Since the reminder 384 ≠ 0, we apply division lemma to 108 and 384, to get
384 = 108 x 3 + 60
Step 3: We consider the new divisor 108 and the new remainder 60, and apply the division lemma to get
108 = 60 x 1 + 48
We consider the new divisor 60 and the new remainder 48,and apply the division lemma to get
60 = 48 x 1 + 12
We consider the new divisor 48 and the new remainder 12,and apply the division lemma to get
48 = 12 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 384 and 492 is 12
Notice that 12 = HCF(48,12) = HCF(60,48) = HCF(108,60) = HCF(384,108) = HCF(492,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 655 > 12, we apply the division lemma to 655 and 12, to get
655 = 12 x 54 + 7
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 7 and 12, to get
12 = 7 x 1 + 5
Step 3: We consider the new divisor 7 and the new remainder 5, and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 12 and 655 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(655,12) .
