HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 953, 639, 857, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 953, 639, 857, 64 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 953, 639, 857, 64 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 953, 639, 857, 64 is 1.
HCF(953, 639, 857, 64) = 1
HCF of 953, 639, 857, 64 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 953, 639, 857, 64 is 1.
Highest Common Factor of 953,639,857,64 is 1
Step 1: Since 953 > 639, we apply the division lemma to 953 and 639, to get
953 = 639 x 1 + 314
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 314 and 639, to get
639 = 314 x 2 + 11
Step 3: We consider the new divisor 314 and the new remainder 11, and apply the division lemma to get
314 = 11 x 28 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 953 and 639 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(314,11) = HCF(639,314) = HCF(953,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 857 > 1, we apply the division lemma to 857 and 1, to get
857 = 1 x 857 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 857 is 1
Notice that 1 = HCF(857,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get
64 = 1 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1
Notice that 1 = HCF(64,1) .
