HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 688, 768, 292 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 688, 768, 292 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, 768, 292 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, 768, 292 is 4.
HCF(688, 768, 292) = 4
HCF of 688, 768, 292 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, 768, 292 is 4.
Highest Common Factor of 688,768,292 is 4
Step 1: Since 768 > 688, we apply the division lemma to 768 and 688, to get
768 = 688 x 1 + 80
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 80 and 688, to get
688 = 80 x 8 + 48
Step 3: We consider the new divisor 80 and the new remainder 48, and apply the division lemma to get
80 = 48 x 1 + 32
We consider the new divisor 48 and the new remainder 32,and apply the division lemma to get
48 = 32 x 1 + 16
We consider the new divisor 32 and the new remainder 16,and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 688 and 768 is 16
Notice that 16 = HCF(32,16) = HCF(48,32) = HCF(80,48) = HCF(688,80) = HCF(768,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 292 > 16, we apply the division lemma to 292 and 16, to get
292 = 16 x 18 + 4
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 4 and 16, to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 16 and 292 is 4
Notice that 4 = HCF(16,4) = HCF(292,16) .
