HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 929, 209, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 929, 209, 77 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 929, 209, 77 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 929, 209, 77 is 1.
HCF(929, 209, 77) = 1
HCF of 929, 209, 77 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 929, 209, 77 is 1.
Highest Common Factor of 929,209,77 is 1
Step 1: Since 929 > 209, we apply the division lemma to 929 and 209, to get
929 = 209 x 4 + 93
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 93 and 209, to get
209 = 93 x 2 + 23
Step 3: We consider the new divisor 93 and the new remainder 23, and apply the division lemma to get
93 = 23 x 4 + 1
We consider the new divisor 23 and the new remainder 1, and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 929 and 209 is 1
Notice that 1 = HCF(23,1) = HCF(93,23) = HCF(209,93) = HCF(929,209) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1
Notice that 1 = HCF(77,1) .
