HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 688, 924 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 688, 924 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, 924 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, 924 is 4.
HCF(688, 924) = 4
HCF of 688, 924 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, 924 is 4.
Highest Common Factor of 688,924 is 4
Step 1: Since 924 > 688, we apply the division lemma to 924 and 688, to get
924 = 688 x 1 + 236
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 236 and 688, to get
688 = 236 x 2 + 216
Step 3: We consider the new divisor 236 and the new remainder 216, and apply the division lemma to get
236 = 216 x 1 + 20
We consider the new divisor 216 and the new remainder 20,and apply the division lemma to get
216 = 20 x 10 + 16
We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get
20 = 16 x 1 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma 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 688 and 924 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(216,20) = HCF(236,216) = HCF(688,236) = HCF(924,688) .
