how to compare between two array that is inside one same array?

i have a code that produce this variable

let matches = [
 [1,3,5,8,10],
 [2,3,5,7,9],
 [1,2,3,5,9]
]

i wanted to find which of these value that appeared on all of these nested array. So in this example, the expected answer would be [3,5]

but i'm stumped on how should the algorithm work

Would be very grateful if someone can help me with this. Thanks in advance!
