HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 654, 524 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 386, 654, 524 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 386, 654, 524 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 386, 654, 524 is 2.
HCF(386, 654, 524) = 2
HCF of 386, 654, 524 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 386, 654, 524 is 2.
Highest Common Factor of 386,654,524 is 2
Step 1: Since 654 > 386, we apply the division lemma to 654 and 386, to get
654 = 386 x 1 + 268
Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 268 and 386, to get
386 = 268 x 1 + 118
Step 3: We consider the new divisor 268 and the new remainder 118, and apply the division lemma to get
268 = 118 x 2 + 32
We consider the new divisor 118 and the new remainder 32,and apply the division lemma to get
118 = 32 x 3 + 22
We consider the new divisor 32 and the new remainder 22,and apply the division lemma to get
32 = 22 x 1 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 386 and 654 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(32,22) = HCF(118,32) = HCF(268,118) = HCF(386,268) = HCF(654,386) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 524 > 2, we apply the division lemma to 524 and 2, to get
524 = 2 x 262 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 524 is 2
Notice that 2 = HCF(524,2) .
