How do we stop all scheduled batch

Question

We had scheduled batch jobs through developer console

System.schedule('Job1', '0 * * * * ?', new scheduledMerge());
System.schedule('Job2', '0 15 * * * ?', new scheduledMerge());
System.schedule('Job3', '0 30 * * * ?', new scheduledMerge());
System.schedule('Job4', '0 45 * * * ?', new scheduledMerge());

Now i want to stop these jobs from running every 15 mins. How can i stop these jobs? If i delete the jobs from Monitoring -> scheduled Jobs.

Try this Apex code in Developer Console Execute Anonymous.

for (CronTrigger ct : [SELECT Id FROM CronTrigger]) {
    System.abortJob(ct.Id);
}
