### Pair factors of 70

• 70/1 = 70 [ 1 × 70 (1, 70) 1 and 70 is pair factor of 70]
• 70/2 = 35 [ 2 × 35 (2, 35) 2 and 35 is pair factor of 70]
• 70/5 = 14 [ 5 × 14 (5, 14) 5 and 14 is pair factor of 70]
• 70/7 = 10 [ 7 × 10 (7, 10) 7 and 10 is pair factor of 70]
• 70/10 = 7 [ 10 × 7 (10, 7) 10 and 7 is pair factor of 70]
• 70/14 = 5 [ 14 × 5 (14, 5) 14 and 5 is pair factor of 70]
• 70/35 = 2 [ 35 × 2 (35, 2) 35 and 2 is pair factor of 70]
• 70/70 = 1 [ 70 × 1 (70, 1) 70 and 1 is pair factor of 70]

As we checked numbers between 1 to 70 that are not leaving any remainder, hence we can say factors of 70 is 1, 2, 5, 7, 10, 14, 35, 70.
