HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 778, 947, 532 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 778, 947, 532 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, 947, 532 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, 947, 532 is 1.
HCF(778, 947, 532) = 1
HCF of 778, 947, 532 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, 947, 532 is 1.
Highest Common Factor of 778,947,532 is 1
Step 1: Since 947 > 778, we apply the division lemma to 947 and 778, to get
947 = 778 x 1 + 169
Step 2: Since the reminder 778 ≠ 0, we apply division lemma to 169 and 778, to get
778 = 169 x 4 + 102
Step 3: We consider the new divisor 169 and the new remainder 102, and apply the division lemma to get
169 = 102 x 1 + 67
We consider the new divisor 102 and the new remainder 67,and apply the division lemma to get
102 = 67 x 1 + 35
We consider the new divisor 67 and the new remainder 35,and apply the division lemma to get
67 = 35 x 1 + 32
We consider the new divisor 35 and the new remainder 32,and apply the division lemma to get
35 = 32 x 1 + 3
We consider the new divisor 32 and the new remainder 3,and apply the division lemma to get
32 = 3 x 10 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 947 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(32,3) = HCF(35,32) = HCF(67,35) = HCF(102,67) = HCF(169,102) = HCF(778,169) = HCF(947,778) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 532 > 1, we apply the division lemma to 532 and 1, to get
532 = 1 x 532 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 532 is 1
Notice that 1 = HCF(532,1) .
