HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 968, 960 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 968, 960 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 621, 968, 960 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 621, 968, 960 is 1.
HCF(621, 968, 960) = 1
HCF of 621, 968, 960 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 968, 960 is 1.
Highest Common Factor of 621,968,960 is 1
Step 1: Since 968 > 621, we apply the division lemma to 968 and 621, to get
968 = 621 x 1 + 347
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 347 and 621, to get
621 = 347 x 1 + 274
Step 3: We consider the new divisor 347 and the new remainder 274, and apply the division lemma to get
347 = 274 x 1 + 73
We consider the new divisor 274 and the new remainder 73,and apply the division lemma to get
274 = 73 x 3 + 55
We consider the new divisor 73 and the new remainder 55,and apply the division lemma to get
73 = 55 x 1 + 18
We consider the new divisor 55 and the new remainder 18,and apply the division lemma to get
55 = 18 x 3 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 621 and 968 is 1
Notice that 1 = HCF(18,1) = HCF(55,18) = HCF(73,55) = HCF(274,73) = HCF(347,274) = HCF(621,347) = HCF(968,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 960 > 1, we apply the division lemma to 960 and 1, to get
960 = 1 x 960 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 960 is 1
Notice that 1 = HCF(960,1) .
