HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 773, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 915, 773, 641 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 915, 773, 641 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 915, 773, 641 is 1.
HCF(915, 773, 641) = 1
HCF of 915, 773, 641 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 915, 773, 641 is 1.
Highest Common Factor of 915,773,641 is 1
Step 1: Since 915 > 773, we apply the division lemma to 915 and 773, to get
915 = 773 x 1 + 142
Step 2: Since the reminder 773 ≠ 0, we apply division lemma to 142 and 773, to get
773 = 142 x 5 + 63
Step 3: We consider the new divisor 142 and the new remainder 63, and apply the division lemma to get
142 = 63 x 2 + 16
We consider the new divisor 63 and the new remainder 16,and apply the division lemma to get
63 = 16 x 3 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 915 and 773 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(63,16) = HCF(142,63) = HCF(773,142) = HCF(915,773) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 641 > 1, we apply the division lemma to 641 and 1, to get
641 = 1 x 641 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 641 is 1
Notice that 1 = HCF(641,1) .
