HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 688, 532, 40 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 688, 532, 40 is 4 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 688, 532, 40 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 688, 532, 40 is 4.
HCF(688, 532, 40) = 4
HCF of 688, 532, 40 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 688, 532, 40 is 4.
Highest Common Factor of 688,532,40 is 4
Step 1: Since 688 > 532, we apply the division lemma to 688 and 532, to get
688 = 532 x 1 + 156
Step 2: Since the reminder 532 ≠ 0, we apply division lemma to 156 and 532, to get
532 = 156 x 3 + 64
Step 3: We consider the new divisor 156 and the new remainder 64, and apply the division lemma to get
156 = 64 x 2 + 28
We consider the new divisor 64 and the new remainder 28,and apply the division lemma to get
64 = 28 x 2 + 8
We consider the new divisor 28 and the new remainder 8,and apply the division lemma to get
28 = 8 x 3 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 688 and 532 is 4
Notice that 4 = HCF(8,4) = HCF(28,8) = HCF(64,28) = HCF(156,64) = HCF(532,156) = HCF(688,532) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 40 > 4, we apply the division lemma to 40 and 4, to get
40 = 4 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 40 is 4
Notice that 4 = HCF(40,4) .
