HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 692, 830, 978, 54 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 692, 830, 978, 54 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 692, 830, 978, 54 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 692, 830, 978, 54 is 2.
HCF(692, 830, 978, 54) = 2
HCF of 692, 830, 978, 54 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 692, 830, 978, 54 is 2.
Highest Common Factor of 692,830,978,54 is 2
Step 1: Since 830 > 692, we apply the division lemma to 830 and 692, to get
830 = 692 x 1 + 138
Step 2: Since the reminder 692 ≠ 0, we apply division lemma to 138 and 692, to get
692 = 138 x 5 + 2
Step 3: We consider the new divisor 138 and the new remainder 2, and apply the division lemma to get
138 = 2 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 692 and 830 is 2
Notice that 2 = HCF(138,2) = HCF(692,138) = HCF(830,692) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 978 > 2, we apply the division lemma to 978 and 2, to get
978 = 2 x 489 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 978 is 2
Notice that 2 = HCF(978,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 2, we apply the division lemma to 54 and 2, to get
54 = 2 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 54 is 2
Notice that 2 = HCF(54,2) .
