HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 694, 20679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 694, 20679 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 694, 20679 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 694, 20679 is 1.
HCF(694, 20679) = 1
HCF of 694, 20679 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 694, 20679 is 1.
Highest Common Factor of 694,20679 is 1
Step 1: Since 20679 > 694, we apply the division lemma to 20679 and 694, to get
20679 = 694 x 29 + 553
Step 2: Since the reminder 694 ≠ 0, we apply division lemma to 553 and 694, to get
694 = 553 x 1 + 141
Step 3: We consider the new divisor 553 and the new remainder 141, and apply the division lemma to get
553 = 141 x 3 + 130
We consider the new divisor 141 and the new remainder 130,and apply the division lemma to get
141 = 130 x 1 + 11
We consider the new divisor 130 and the new remainder 11,and apply the division lemma to get
130 = 11 x 11 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 694 and 20679 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(130,11) = HCF(141,130) = HCF(553,141) = HCF(694,553) = HCF(20679,694) .
