HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 824 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 824 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 654, 824 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 654, 824 is 2.
HCF(654, 824) = 2
HCF of 654, 824 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 654, 824 is 2.
Highest Common Factor of 654,824 is 2
Step 1: Since 824 > 654, we apply the division lemma to 824 and 654, to get
824 = 654 x 1 + 170
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 170 and 654, to get
654 = 170 x 3 + 144
Step 3: We consider the new divisor 170 and the new remainder 144, and apply the division lemma to get
170 = 144 x 1 + 26
We consider the new divisor 144 and the new remainder 26,and apply the division lemma to get
144 = 26 x 5 + 14
We consider the new divisor 26 and the new remainder 14,and apply the division lemma to get
26 = 14 x 1 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 654 and 824 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(144,26) = HCF(170,144) = HCF(654,170) = HCF(824,654) .
