HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 654, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 654, 679 is 1 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, 679 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, 679 is 1.
HCF(654, 679) = 1
HCF of 654, 679 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, 679 is 1.
Highest Common Factor of 654,679 is 1
Step 1: Since 679 > 654, we apply the division lemma to 679 and 654, to get
679 = 654 x 1 + 25
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 25 and 654, to get
654 = 25 x 26 + 4
Step 3: We consider the new divisor 25 and the new remainder 4, and apply the division lemma to get
25 = 4 x 6 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 654 and 679 is 1
Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(654,25) = HCF(679,654) .
