HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 573, 930 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 573, 930 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 778, 573, 930 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 778, 573, 930 is 1.
HCF(778, 573, 930) = 1
HCF of 778, 573, 930 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 778, 573, 930 is 1.
Highest Common Factor of 778,573,930 is 1
Step 1: Since 778 > 573, we apply the division lemma to 778 and 573, to get
778 = 573 x 1 + 205
Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 205 and 573, to get
573 = 205 x 2 + 163
Step 3: We consider the new divisor 205 and the new remainder 163, and apply the division lemma to get
205 = 163 x 1 + 42
We consider the new divisor 163 and the new remainder 42,and apply the division lemma to get
163 = 42 x 3 + 37
We consider the new divisor 42 and the new remainder 37,and apply the division lemma to get
42 = 37 x 1 + 5
We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get
37 = 5 x 7 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 778 and 573 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(42,37) = HCF(163,42) = HCF(205,163) = HCF(573,205) = HCF(778,573) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 930 > 1, we apply the division lemma to 930 and 1, to get
930 = 1 x 930 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 930 is 1
Notice that 1 = HCF(930,1) .
